The funny thing about Genesis is that there was never any actual evidence that Khan himself planned to use it as a weapon on anyone. (I mean I can hear the rationalizations coming: he's Khan! He's evil! Why wouldn't he! But the whole point about Khan, even in TWOK, was that he was evil within certain bounds, a Napoleonesque figure who cared about his personal prestige but also about building as well as destroying.) Kruge totes wanted to weaponize it in the next movie, but AFAICT Khan's whole game was that he wanted a habitable planet for his peeps after the ordeal they went through.
That said, the "villain-with-a-death-ray" trope is way overused in Trek movies. I'll completely cop to the Arbonath being an example of that, although somehow it seems less stupid than "red matter" did despite its function having been made no more specific. I wouldn't be sad to see the back of it.
