Yes, I always think of the psych speak statement, "Hurt people hurt people."

Look back far enough into any atrocity and you see some traumatised young kid who's given a weapon and no therapy, and hasn't got the virtues of character that allow most traumatised people to not go...uh...Bad Crazy. Heck, entire civilisations have relied on that trauma as a way of building oppressors.

That doesn't mean that the people who do such things shouldn't have consequences, only that it's gonna happen, and at some point we need not bland lib forgiveness or "The Wall" but the fraught process of giving Equity, followed by Truth and Reconciliation.
