Anger and desires to kill and maim innocents are sometimes normal human reactions, but they should be demonized. So should jealousy, as it is basically a form of anger.
Burying anger is not healthy emotionally. When you demonize emotions that a person naturally feels you demonize the person and they only internalize the pain. Do what works for you but don’t be a nuisance to everyone around you by making them guilty for things they can’t help.
I've buried a lot of anger over the years and I'm fine.
