There is indeed something deeply wrong with a person who lacks principles, who has no moral core. There are, likewise, certainly values that brook no compromise, and I would count among them integrity, fairness, and the avoidance of cruelty. But I have never accepted the argument that principle is compromised by judging each situation on its own merits, with due appreciation of the idiosyncrasy of human motivation and fallibility.
Turn yourself inside out. Live with absolute certainty that you have the power to create anything that you desire-anything!-because the power you need is the power of the Universe flowing through you.
