There are several characters as seen in the drawing I've made for this post, such as (from top left to right bottom order) Aizen from Bleach, Griffith from Berserk, Makima from Chainsawman, Cossette from Le portrait de petit Cossette, Eren from Attack on Titan, Pain from Naruto, Kaname from Vampire Knight, and Sukuna from Jujutsu Kaisen.
These villains were villains with different purposes and reasons. Some were manipulative and bad from the beginning, some were driven by their backgrounds and pitiful fate they've gone through and some were forced by their own condition to turn bad in the process. One thing in common out of all is they were mostly powerful.
Somehow I personally can relate with them in a way of picturing them as characters of some normal human can be in reality. Apart from how evil they were, they live for a purpose in the story.
