Westcott has a tragic past I thought.

Ehhh... it hardly excuses his actions. If I recall, he even admitted this.

Well he's pure evil no doubt. But I would have had Dimentio or Sidous as "just evil". But tragic villains are my favorite. Lotso, Count Bleck, Killing Joke, Telltale and 2019 Joker etc.

I personally think that redeemed villains are the best. You get to see their journey from a villain to becoming a better person. Also, a lot of redeemed villains also have interesting backstories and reasons to redeem themselves, making it 2 in one.

I love all of them as long as they are well made. But as I had to choose... I’ll go for pure evil, I looooove them !!!

Hard one tbh. I will admit that I like PE villains because it's really fun to read their rapsheet but hey! Magnificent Bastards needs more love too.
