I actually felt some sympathy for the prisoner. He went into Prison at 19. Perhaps he was even younger when he committed murder. WTF does a teenager know about themselves or the world to kill someone?! What kind of awful childhood and upbringing environment did he experience, if any?

Of course he could be a psychopath. Or who knows. I wouldn't presume anything. But I wouldn't be so righteous feeling good about myself for not doing what he did. We're all lucky we didn't have it so bad, be it nature or nurture, or both.
