the.com/moral high ground

The one hill everyone dies on, armed only with righteousness and zero supplies.

means A position of moral superiority claimed in an argument or conflict, usually to win it without needing better facts or tactics.

from A 20th-century metaphor built from military language — 'high ground' being the literal tactical advantage of holding elevated terrain in battle, from which you can see farther and strike down harder. Moralists borrowed the image wholesale: instead of a hill made of dirt, it's a hill made of being right, and instead of cannons, you fight with the implication that you're better than the other person.
