Agree to disagree. It depends upon the circumstances.
Sorry, circumstances don’t come into it at all.
Nope. If there is no higher authority than man then man can make his own rules. I don’t have to respect you nor do I have to care about your welfare. You are nothing to me. There is no god to say differently. As long as I don’t get caught I can treat you anyway that I please including cheating and stealing from you. If I don’t get caught there is no price to pay. You don’t matter a whit, only what I think is right matters.
