You only think I’m hurting myself because you don’t understand what having principles means, and that violating them would hurt more than any monetary penalty. Whether it hurts the other or not is completely irrelevant to my decision. But it makes sense that you think in zero-sum terms, people without principles usually do.
Edit: You edited your comment so mine is now irrelevant.
You seem to think that “pragmatic” and “rational” have universal or objective definitions, which is completely untrue. For example, depending on if you have a short term or long term view of a situation could completely change whether an action is considered rational or not, and vice versa, and has absolute nothing to do with any moral framework.
Principles and morality are not the same thing, so no, incorrect. I could have completely amoral principles. Morals are grounded in social consensus, principles are not.
Spend less time trying to be right and more time learning.
Of course, a complete lack of self awareness is also a common principle-free, sociopathic trait.
