I laugh sometimes when I watch videos of really bad car crashes and someone goes flying through the air
You sound like you're watching a cartoon. What is so funny about videos of people suffering crippling, painful injuries and death?
It amuses me that someone can be hurt or even worse dead, without noticing that someone else would care.
You should not be entertained by the death of others. It is insensitive and rude.
When you relate it to bullying, it's even more funny.
Your lack of empathy is deeply disturbing. If you think bullying people to the point of injury and death is hilarious, you need to seek help.
