Ya but old and new have new rules written not by God but by people. Like you and me Suicide rating back when God was invented- approximately 76% I believe Kings and queens used God as a mean to add power (supernatural) to theirs. Why do you think most every sin would benefit a king or queen? It's not a coincidence. Also people are fascinated by the fact that we don't know where we go after death. Religion answers that. So it's a way to sugar coat bad things as well.
