Yes. And some people's perceptions are bad.Bad is determined by your perception.
I would also celebrate that someone's death.Because of morals and perception, if I died literally right now, someone would feel the world is a bit safer because of intrinsically who I am. Because I am a bad person in their minds.
You can, but fuck anyone who loved such a monster. If they're grieving him, they're bad too.Y'know, you can feel more than one way about somebody's death. Y'can feel glad that his direct negative influence on American politics/ culture has ended, and you can also feel sympathy for family members/ friends who might be grieving.
