Road to Hell is paved with good intentions, this quote seems to fit Light Yagami a lot.
Gojo Satoru is a teacher at Tokyo Jujutsu High, a special grade jujutsu sorcerer and the strongest sorcerer.
He’s a teacher and also the strongest in Death Academy. He has strong urges to dissect anything, whether he likes it or not is none of the concern.
Hisoka is perhaps one of the most disturbing characters on Hunter x Hunter. A pure sadist with hints of masochistic tendencies too, he gets aroused in killing and spilling blood whether it’s his or his opponents.
The infamous Gourmet ghoul, a human meat enthusiast until he got obsessed with the smell and taste of Kaneki Ken. He has no repulsion in showing his obsession towards him, getting angered at another ghoul who tries to eat him.
The strongest Esper in Academy City with the power of vector manipulation. No one can literally touch him unless he wants to
The strongest in the Hellsing Organization, he fights with ferocity and cruelty, sometimes even eats his opponents or leaves them humiliated or dismembered. Being immortal and invulnerable, on top of that.
A chatty sadist who finds amusement in killing people. He loves to kill people who are deemed ‘untouchable’ or ‘invincible’, finding all of it as an entertainment. He even thanks people he has killed for the entertainment.
