For as long as I can remember I get REALLY anxious and uncomfortable if I see someone getting in an awkward situation where people get mad or think bad of that person or he makes a fool of himself even if only slightly and for a little amount of time.

This happens even if it's all fictional as in in a show or movie or video game etc. For example if the main character fakes doing something wrong in front of other people getting them disappointed temporarily so that he can foil the bad dude's evil plan, I feel like turning the tv off and to never watch it again. Many times I really do that, there are movies and animes etc I suddenly, permanently quit because of that.

I know this is stupid and abnormal. I don't want to remain like this. But no matter how much I try I can't convince my brain to stop this. Why does this happen? What do I do?
