&gt; Morality is, unfortunately, subjective.<p>Genuine question: What do people who believe this use as their reason for refraining from harming others for personal gain? I understand that simple intuitive preferences against seeing others suffer will often work, but what do you do about instances where either the rewards of screwing someone over are very great or where your intuition tells you that you would get a lot of pleasure from seeing someone in pain?<p>I know that I don&#x27;t really have anything to support my belief that there exists an objective morality which is hard-to-determine.
