What does moral conscience mean?

Your moral conscience is your sense of what is morally right and wrong (e.g., “Members of Congress often have to vote along party lines rather than according to their moral conscience”).

On a related note, if you’re not sure whether the word you need is conscience or conscious, bear in mind that “conscious” is an adjective that normally means “aware,” but “conscious” is a noun referring to your sense of right and wrong.
