It's easy to hate on him, but I know some people that are drug addicts, and they never recover. Once you're on hard drugs like he is you're on a slippery path towards death and there's little you can do about it. He's done so much crazy stuff and he'll never stop.
Sadly....this is true. There is something in Tapia's life that he has not forgiven himself for yet and it is leading him further down the path of self destruction.
