I'm not religious, but one of my ideologies is to do unto other as you would have them do unto you.
I think if everyone treated others the way that they would like to be treated, then the world would be a better place.

That belief was created and pushed by religious, political, and business elites who themselves did not give equally to other people or treat them fairly. They always schemed out more for themselves. Your rule is best modified to do onto others as they would actually do onto you to the best of your knowledge. Otherwise, your rule will result in more evil happening overtime as the good people will work within the schemes created by the bad people. That's already happening.

Even includes retaliators which are relevant here.
Maybe that is too cynical, but it works well as a rule of thumb.
