In the realm of anime, the concepts of good and evil can appear rather straightforward. Protagonists typically don bright, vibrant colors while antagonists tend to dwell in shadowy corners. Justice seems to emerge victorious more often than not. However, the truth is that the most intriguing characters often inhabit the complex gray areas that lie between these clear-cut definitions.
These characters make choices that provoke deep reflection; decisions that elicit mixed emotions of defensibility and condemnation. They may kill in pursuit of peace, lie out of love, or adopt abhorrent behaviors to shield those they care for. Some characters begin with noble intentions only to falter along the way, while others are born from darkness and strive to experience the essence of being human.
This list showcases individuals who are multifaceted, deeply flawed, and tragically relatable. Their actions prompt us to confront challenging queries: Is it intention that holds greater value than the outcome? Does the instinct for survival justify acts of violence? Ultimately, what does it mean to embody “goodness”?
7. Rudeus Greyrat
Mushoku Tensei: Jobless Reincarnation

Rudeus Greyrat stands out as a highly polarizing protagonist. After dying as a reclusive NEET, he is reborn into a fantastical world, retaining all his former memories. This unique premise lays the groundwork for a narrative rife with moral complexities, as he consciously strives to reshape his life while grappling with past mistakes and lingering desires.
From the outset, Rudeus exhibits significant flaws, particularly in his interactions with women during the first season, which raised numerous eyebrows among fans. These tendencies establish a divide in the audience: some view him as a character earnestly striving for redemption, while others perceive him as someone misusing his second chance.
Nonetheless, Rudeus is intentionally crafted to defy the archetype of a role model; his development serves as the crux of the story. By Season 2, especially during the labyrinth arc and his marriage to Sylphiette, viewers witness a subtle but critical maturity. He learns to sacrifice, embrace responsibility, and expand his scope beyond mere self-serving motivations. The narrative does not shy away from addressing his earlier misdeeds; rather, it highlights them. He confronts his own PTSD, struggles with trauma-induced dysfunction, and battles a profound fear of abandonment amidst a harsh world that mirrors his complexities.
This duality—being at once a sinner and a savior—renders Rudeus a quintessential morally gray character. Neither wholly good nor entirely evil, he encapsulates the very essence of humanity. In a genre often populated by archetypal heroes and monstrous villains, his character profoundly resonates.
6. Alucard
Hellsing

Alucard is a vampire who doesn’t seek redemption; rather, he embraces his monstrous nature, choosing to channel it as a force against evil. Bound to Integra Hellsing, he relentlessly hunts down threats to the British Empire, from ghouls to nefarious vampires, carrying out his tasks with brutal efficiency.
Despite his overwhelming power, it’s Alucard’s willingness to serve Integra that speaks volumes about his character. He permits himself to be controlled and demonstrates unwavering patience, awaiting orders, even from a mortal who trembles in his presence.
The depths of his character unfold later in Hellsing when his past is revealed. Once known as Vlad the Impaler—Dracula himself—he sacrifices his freedom for a sense of purpose, but it is not a quest for redemption; instead, it is a quest for purpose.
Where villains may boast about their moral high ground, Alucard acknowledges his damned nature. This awareness ironically renders him more honorable than many who delude themselves into believing they are righteous.
5. Sasuke Uchiha
Naruto

Throughout the series Naruto, Sasuke stands as a character who isn’t a straightforward villain, yet remains detached from any side other than his own interests.
The lone survivor of a clan massacre, his life is dominated by a quest for vengeance against his brother Itachi. This obsession leads him to sever ties with his village, culminating in an alliance with Orochimaru, an enemy of Konoha, marking each move a deliberate act of betrayal.
However, everything shifts upon discovering the true nature of Itachi’s actions, revealing that the massacre was a covert mission mandated by the village’s leaders. This revelation spirals Sasuke’s morality into further turmoil, redirecting his hatred towards Konoha itself. He boldly declares his intention to become a villain if it means crafting a better future.
Thus, his rebellion is not without purpose. Sasuke clings to a distorted ideology: achieving peace through authoritarian control. Following the Fourth Great Ninja War, he suggests assassinating the Five Kage to impose a singular rule, an idea as tyrannical as it is pragmatic.
4. Spike Spiegel
Cowboy Bebop

Spike Spiegel’s narrative arc is not one of epic heroism but rather a portrayal of survival amidst chaos.
Having once served as an assassin for the Red Dragon Syndicate, Spike fakes his own death and reinvents himself as a bounty hunter aboard the Bebop. However, his past continually haunts him, primarily through his ties to Vicious and Julia. Unlike traditional heroes, Spike’s motivations are not about justice; instead, he fights simply because avoiding his past is no longer viable.
Often perceived as indifferent and emotionally detached, Spike’s demeanor conceals layers of pain. He employs apathy as a shield against emotional connections, particularly with his fellow crew members, Faye and Jet, which stems from his belief that tomorrow is a luxury he can no longer afford—having already died once.
He often engages in menial jobs that yield little reward, fighting battles that are ultimately inconsequential, all while smoking as if counting down his own fate. Yet when old demons arise, he steps forward willingly, brandishing a weapon and fully aware it could lead to his demise.
Spike never seeks atonement; perhaps he never desired it. He perceives a world beyond repair, in which individuals like him are destined for death.
3. Tenth
Death Parade

Decim serves as an arbiter, tasked with evaluating human souls after death, determining whether they should be reincarnated or cast into the void. His role ostensibly lacks human emotion—but that’s precisely how it’s designed.
In a system based on simplicity, two deceased souls are brought to a enigmatic bar to engage in games that compel their darkest memories to surface. Observing these encounters, Decim watches, assesses, and ultimately adjudicates their fate. However, his encounters with Chiyuki, a woman who challenges his understanding of morality and sentiment, compel him to reconsider the very system he upholds.
While Decim is not malevolent and does not revel in suffering, his stance of neutrality embodies a form of cruelty. He subjects individuals to extreme conditions, knowing they will break, and he uses this to shape their eternal destinies.
Eventually, Decim begins to experience genuine emotions, leading him to abandon the rigidity of pure logic in favor of empathy. His journey culminates in moments of vulnerability: he cries, he smiles, and he defies the established rules.
2. Lelouch Lamperouge
Code Geass

Lelouch vi Britannia embodies the complex roles of a revolutionary, a terrorist, and a self-identified tyrant. Nonetheless, he claims to be motivated solely by his desire to protect his sister Nunnally and to realize a more compassionate world.
Gifted with the power of Geass, which allows him to compel obedience from anyone, Lelouch launches a war against the Holy Britannian Empire—the very regime of his birth. Under the guise of Zero, he becomes a beacon of rebellion, yet his methods are riddled with manipulation, deceit, and the sacrifice of countless lives.
Perhaps his most disturbing act involves the unintentional use of Geass that leads to Euphemia, a peace-seeking princess, to slaughter innocents. Rather than capitulating to despair, Lelouch exploits this tragedy, using it as a foundation for his revolution.
Eventually, Lelouch engineers the Zero Requiem, wherein he bears the world’s hatred upon himself, presenting himself as the archetypal tyrant. In a heart-wrenching twist, he orchestrates his demise at the hands of his closest ally.
In his final moments, Lelouch dies a villain, paving the way for peace to emerge in his absence.
1. Ken Kaneki
Tokyo Ghoul

Ken Kaneki’s evolution in Tokyo Ghoul represents one of the most harrowing transformations in anime. Initially an innocent literature student, he becomes enmeshed in a violent struggle after a botched organ transplant leaves him a half-ghoul.
In the beginning, he resolutely rejects the notion of killing, holding fast to his human ideals. However, the brutal nature of the ghoul world, characterized by predatory instincts, enables no room for such naivety. After enduring horrific torture at the hands of Jason from the Clowns, Kaneki breaks, underlining his transformation with stark physical changes—his hair turns white, and his old ideals shatter.
Yet, despite his brutal ascent to power, Kaneki never fully relinquishes his humanity. He devises safe havens for weaker ghouls and chooses mercy when feasible, even though his actions lead to violence. Killing is not a source of pleasure for him; instead, it becomes a means to safeguard those he cherishes.
Later, under the identity of Haise Sasaki, he exists as a ghoul investigator with no recollection of his past. However, as memories resurface, he grapples with the complexity of his identity. Is he a monster? A man? Or a fusion of both?
Kaneki is far from a traditional hero; rather, he is a reflection of human suffering, embodying the devastating intersection of kindness and cruelty, revealing how ambiguous moral lines can become when survival hangs in the balance.
