Principles only truly matter when abiding by them causes oneself harm or others harm beyond the benefit of abiding by those principals. If abiding by a principal is already advantageous to yourself or society then you would follow it. The rubber meets the road when abiding by a principal causes suffering.

Are you principled or do you approach things solely through the lens of self gain and utilitarianism?

A classic example is politics - would you do something vile, even downright evil and harmful to others? Despite a moral propensity not to do so if it led to electoral gains for the party you support that you felt would benefit society more in the long run than the people you harmed?
