I do the same thing. I think it is because we are sensitive and have empathy for the person or character. I always think how I would feel if that situation were happening to me. In a way, I don't think that's it's really a bad thing. I think it shows that we care about other people and do not want to see them hurting or feeling uncomfortable.

I don't know if there is a way to really stop feeling this way. I would just keep doing what you are doing and avoid watching those situations as much as possible. If it's on tv, video game, etc, then turn it off like you have been.

If it happens in real life, maybe you could stand up for the person getting humiliated. This might make you feel better because at least you tried to help. You may get a new friend out of it, too.

Wish I had better advice. I will be watching this thread, as well, to see what others have to say about this problem.
