It's called CONSEQUENCES.
This moron made a choice to make meth. That has consequences, for him AND his family.
He should have thought about it before he he made such a stupid decision.
Yes, I realize he didn't know his daughter was going to get cancer and die, or that he thought he wouldn't get caught or whatever, but those are the risks you take. When my kids were little, they NEVER rode in the car without being in their carseats. Yes, 99 times out of 100 it woud have been fine, but that ONE % chance of something going wrong wasn't worth the gamble to me. The risk was a price I wasn't willing to pay.
People have to learn that actions have consequences, and act accordingly.
