That father may not have been able to physically help them, but he could have spoke to his son and encouraged him - even if he was unconscious. As it turned out, he lost that opportunity on this earth. Hope these pompous, control freaks are pleased with themselves.

And what he should have done is walked the father over and stayed with him there...
