I find it's a lot easier and effective to have integrity if you have a practical moral code that aligns with human nature/emotions instead of platonic societal ideals of integrity. For instance, not cheating is a big one that I have disagreement with. We are naturally inclined as humans not to be monogamous, so to feel guilty for wanting to cheat or even going through with the act is self-defeating. More important are questions like the "why" of cheating than the "what". Is the relationship dysfunctional? Is it just a fling? etc etc. And are my or my partners life actually negatively affected by it? Do you have less integrity if you cheat? Maybe. But I think integrity is the art of balancing societal expectations, platonic ideals, and actual human nature/instincts. Adhering to a strict moral code doesn't make you a good person. If anything it makes you bitter, narcissistic, and resentful of other people. Contributing to society on the whole is what counts.
