If morality is subjective and right and wrong varies between individuals…..does that mean war isn’t right and wrong? Just a thing that happens over time?

I’m not big fan of war either way, just seeing innocent civilians losing their love ones and really just suffering…makes me question why we glorify and support it regardless…but then again there’s some people out who think having sex with children is okay.

I know this has noting to do with nihilism but idk morality bugs me most of the time.
