This probably also raises if you incorporate people who were traumatized as children. Someone having a trauma response can definitely look like horrible ego-centric behavior, when actually they're having an internal meltdown where they're emotionally re-experiencing their trauma with no coping mechanisms because we basically never teach adults to recognize when this is happening.

A lot of hyper-toxic fiddly freakouts over small things actually turn out to be deeply rooted in some sort of horrible trauma.
