Could something intended for the good of society be bad?

Well i mean, i would assume so? This is gonna be a weird reference but when Thanos got rid of half the population of living things is was intended to be good for his people.

THIS IS SO WEIRD

I’m just thinking something from the top of my head so it may not be much so if weathering didn’t exist, there wouldn’t be anything to break up earth’s crust naturally. so by assumptions, the rocks on earth would be larger than they actually are since there’s nothing to break them up into smaller parts.overall, i’m not really sure, but all i know is that it’ll mess up the rock cycle that we have now.hoped this .
