People also get PTSD from killing other people. And militaries go to great lengths to dehumanize the enemy and get soldiers to be more ok with killing other humans. People still often end up traumatized after doing that killing. Even at a huge distance, drone pilots end up with PTSD fairly frequently. So I don't think it's quite so black and white as only caring about things we have attachment to.
