Is morality objective or just opinion?

Welcome to the debate arena! Today's topic: "Is morality objective or just opinion?". Your opponent's style: Devil's advocate

Morality is an objective idea because it is truly just an expression for human emotion. Let's say I show you a picture of a man torturing an innocent child, I then ask you to point out the immorality, where is it?

You just proved the opposite. That revulsion you feel? That's *your* emotion, not objective truth. Show that same image to a psychopath who feels nothing—suddenly the "objective immorality" vanishes. If morality lived in the act itself, everyone would perceive it identically. They don't. You're calling emotions facts because they feel universal. They're not.
