The only principle you ever need to know to live a Biblical Godly moral noble virtuous etc. ad-infinitum is – Never abuse… never ever, ever never, may you nor anyone abuse – Even if someone abused you! – You see, we all have love and an ego. – Our love says "unite;" so to unite, we must be kind; Our ego says "no-one may ever be better than me!" – So when we love and someone has something good we are happy for them for as we identify (see ourselves in them) it’s as if we succeeded; But when we feel abused, (hence we disassociate – stop identifying – with others) our ego says "that wasn’t right!!" we become angry hence miserable hence jealous hence malicious (the fact it’s our ego, not our love/soul/mind, is that when someone else gets abused, at best if we are truly holy, saintly and noble, we feel what happened is reprehensible or deplorable; but it doesn’t create an emotional reaction, for all emotions are tied into our ego – they ultimately feed "me".)
