I think that harming others is an indirect method of self-destruction. I cannot explain it fully right now, but in terms of child abuse, I think it's a form of "no boundaries" when lashing out at the child is a way to attack one's inner child.
Inner critic/outer critic. Externalizers give the abuse, not take it on and enact it on themselves, as in cutting or other self-harm.
Externalizers + mental illness (Axis II disorders) + unhealthy lifestyle/drugs + _____ = abuser. Anger is not even part of the equation. It leaks out in there someplace, but so does every other emotion. Anger is just much more visible/vocal but so is shaming/humiliating someone.
