We don't know the root causes in this specific case, just the outcome. Barring a psych eval, we have to assume this is just a violent person, and restrict their freedom appropriately. In the end, it doesn't really matter the root cause, since we can't go back in time to ameliorate those factors; violent criminals need to have their freedom restricted. I'm not talking about "criminals" who misunderstand the law and get caught in a technicality. That's your strawman. I'm talking specifically about a violent person committing assault and battery.
