Its not so much the violence and brutality that gets to me, its who that brutality is inflicted upon. If I saw a snuff film, someone getting tortured to death, and I was under the impression the torture victim in the video was a child molesting animal abusing rapist murderer that pollutes, I'd cheer on the process as if I were watching a hockey game. But if I were under the impression the torture victim was a random person that did nothing wrong to anybody, that would 'get to me' and make me really angry and sad.

Basically any case that involves somebody I don't want on Earth harming people that I don't mind having on Earth, very guilty people harming innocent people, or far less guilty people, however you want to look at it, that bothers me the most.
