This is basically Objectivism.
Wouldn’t it be cool if people who committed violent acts couldn’t actually be traumatized by those acts if they were unambiguously immoral. If people who did Evil were always consciously aware of it. If there was a moral order to the universe manifested in our bodies and in our works. One could then be sure that anyone who committed an act of evil and reported being traumatized by it was really lying.
I hope these IDF soldiers wake up. You can’t kill people without killing part of yourself.
