He's in debt, his wife has life insurance. They go to a fucked up part of SA, they let the dude go free, but kill his wife with NO sexual abuse. For shits and giggles?
Such a lame for a marriage when one side/either the man or woman, is silently roughing up the other side for evil purpose. But that's life is. Not judging that this was right but life is too complicated to see through. Tough life he been through.
