The one thing that all drug addicts have in common is that they're
selfish. They don't care who they hurt as long as they get their fix. This woman left him in a garbage can so she could go and get her fix. Getting that high was more important to her then Isaiah's safety. And then you have that ridiculous arguement of "he's black so he should go with his black mother" used by her lawyer (don't get me started on that. PLEASE).
Money isn't the root of all evil. Love of money is.
