I said it before, I'm usually pretty sympathetic to guys who do stupid things as teens, particularly at an age where I was still in middle school. However, certain behavior is just totally beyond the pale and to this amateur psychologist, symptomatic of major character flaws in a person. At 14, unless Miller himself suffered from some developmental disability, you should still have some ability to feel empathy. The complete disregard shown for another human, another human that himself was incredibly vulnerable is just really, really troubling. And if it's true that he hasn't personally apologized to the victim, and that his camp wasn't totally forthcoming with the teams that interviewed him, it shows that there is still a major problem manifest in this guy's life. Whether he himself is an actual psychopath, or whether he's just very troubled and has a bad support system, it seems pretty clear he's still a problem.
Playing professional hockey is a privilege, and even though he was young, I feel like the act and continued questionable behavior has him forfeit that privilege.
