Can our feelings tell us what is right and wrong?

Our emotions reveal that we have convictions about what is right and wrong. If this were not the case, we would never feel frustrated, indignant, or even angry when we see or experience injustice. No one ever says, “That is not just! But don’t worry about it because my sense of right and wrong has no connection to an objective standard of justice. It’s just my own personal truth.”

But these ethical convictions we have, are they always right? Put another way, are our feelings accurate 100% of the time about what is right and wrong or are they sometimes unreliable?
