I think watching them regularly, especially on sites like Liveleak and sites worse than Liveleak, is a sign you're a social retard, but not much else. I've known plenty of normies that will somehow involve death/murder/gore videos in their epic group chat banter and they don't for a second question whether this means they are somehow mentally ill, sadistic or dangerous. Most 13-35 year old males that I have spoken to have watched and at some point sough out gore videos
People who sit at home with fuck all to do and fuck all social interaction are dying to think that there is something wrong with them that justifies why they are so useless and they think that just because they've watch a gore video that has been viewed 3.2 million times they are
a unique epic gamer with only time separating them from their first kill, when in reality they are extremely mundane and doing the same shit as everyone else
But I'm a schizophrenic so maybe don't listen to me
