The blame the victim mentality here is getting ridiculous. We don't blame women when they are raped so why do we blame people for getting thieved. Everyone takes risks in life they regret and misjudges others' characters, I'm sure even Joel has done it. It doesn't make them an immoral person
There's nothing wrong with blaming the victim when the victim is in fact at fault. The error in blaming the victim is when you attempt to use blame for the victim to excuse or reduce the culpability of the perpetrator.
If you walk through the worst neighborhood on a dark night with $100 bills sticking out of your pockets and get robbed, you're an idiot who deserves some blame for the robbery. However, the robber certainly can't use this to reduce his culpability. There's no "he was asking for it" defense to robbery.
