Indeed. But we won't prevent you from saying your character is "cold, ruthless, murderous, insane, dark, detached, uncaring, calculating, devoid of emotion etc."

Those words describe the characteristics of a character's personality, and we do not deny you that right. We don't want words like "good" and "evil" being used because they are opinions not facts. Hitler is widely considered evil, but supporters of the Nazi party didn't consider him evil. It was a matter of perspective. He was viewed as "evil" buy the rest of world, but he was seen as a hero by Germany. Wikipedia does not once declare him evil in their article unless they're writing about someone else's perspective on him. The same is being applied here.

So we'd simply prefer to say "He/she is known for incredible coldness and murderous intentions," over "he/she is very evil" because we don't use opinions on an encyclopedia-based site. That's all that we're trying to establish.
