So he was bad for what he did in Iraq, but...
... in Kosovo and Sierra Leone, especially Kosovo, many people consider him a hero and even children are named after him.
So that means in 1999 with UK's military intervention in Kosovo he was a hero but even since deciding to invade Iraq he has become a massively despised real life villain who is responsible for deaths of a million people, and also allegedly lied deliberately about Weapons of Mass Destruction to go to invade and in UK many feel he should get a life sentence for it.
But he wasn't evil for what he did in Kosovo though, right?
