Scientific studies have shown that curse words relieve physical pain better than any alternatives.
So there are some situations where anything else is an objectively worse option.
ETA: I’m willing to bet the reason this is being downvoted is due to the holier-than-thou attitude you’re copping, OP. It’s also something of a classist-coded cliché to claim that people who curse lack vocabulary, intelligence, education, or creativity. This is, of course counter to the fact that studies have shown that people with higher intelligence are more likely to use salty language.
