"What happened to "judge not, so you shall not be judged likewise?"
Were they judging his sins too?
Look, the minute they came upon this guy, their little recreational field trip should have ended. Whether or not the guy would have made it is immaterial--we never know now, because he was left up there to die. So you're also suggesting that people brought into an emergency room should not be medically treated "because he probably won't make it anyway" all based on the assumption of condition?
Everyone of those SOBs are murderers.
I've been very clear in saying I think they had a duty to stop and stay with him, even if they couldn't save him.
But I'm equally clear that it's a moral failure, not murder. They didn't kill him. There's no reason to believe they could have saved him. Their failure was moral, not legal, and it wasn't murder, but lack of compassion.
