how do you write an interesting antagonist race? ive been working on a scifi project ive had kicking around for years, i finally managed to make the humans very interesting but now the evil aliens feel rather dull; theyre little more than vehicles for the plot to move forward, mindless, violent savages with not much deeper to them. the humans comparatively have alot more going on culturally, socially and psychologically. im trying to think of things to make the aliens more interesting but its harder to think of how an alien culture would diverge in thousands of years, im trying to write an entire background and lore for them and sometimes i feel its pointless and i might as well just use them as le ebul ayylmaos

im trying to keep the basic idea of warlike aliens at the very least but im willing to make some changes considering how many ive made to the humans
