How Do I Feel When People Don't Follow the Rules?

Ask yourself, what if these people just have different and finely tuned belief systems from me?

How would it feel if i instead transferred my energy to forgiving this person right now, rather than condemning them? Would a harsh reaction be as efective as a compassionate one? Ok?
