That's reading quite a lot into an article which I don't believe supports those positions. We know nothing about the circumstances of the murder, nor of the riot, nor of his upbringing. There's absolutely nothing in this article to even suggest he's a psychopath.

For all we know, he was in the wrong hood at the wrong time, and had to adapt to "prison life" because that is the culture that is foist upon him.

I'm not saying he's not a psychopath, but that's not an evidence-based assertion here.
