Which is one good reason to not to follow anything blindly. Anything that's treated as a religion, politics, gods, sports teams, etc. . Gotta use your own intellect to develope your own morals and ethics.
Comes down to what I've said on the subject of good and evil, applies to morals and ethics as well. What people are willing to accept.....
I have reservations on the existence of conscience as well. Again, an issue that is totally subjective. I Have no conscience, but I know right from wrong, at least what is accepted as right from wrong. I have no issues doing wrong, but just knowing it's not accepted as right prompts a mental note to not do it or that. To me, breaking someones arm is no more disturbing to me than flipping a light switch.
Probably the same with these so called leaders that tell you what is right from wrong, good or evil, or what YOUR level of morality or ethics should be. Our current society has thrown all that out the door.
