I think we generally underappreciated just how little separates all of us from behaving just like him, and overestimate how much of his behavior is because of choice as opposed to circumstance.

I agree 100%.

This is a description of fundamental attribution error to a T. Simplifying human beings actions into a representation of their character rather than looking at the circumstances and conditions that resulted in making the decision to begin with. We overestimate our inherent differences, in order to distance ourselves from unsavoury behaviour and boost our own self esteem.

And there is no place for profit in keeping people safe (both the offenders and society at large).
