Yeah that makes no sense. Why would give Beerus care? If he's fine with someone destroying them and their populations he wouldn't care to revive them. Not unless there's so weirdly specific selfish reason to do so. And even then, it'd be pretty hard to write while staying true to Beerus's egoistic and selfish character. Only reason he'd do it is for food or something, and even then, why would he even bother if he was complacent with their destruction? He'd probably just assume they didn't have good food and shrug it off.
How would you write this while staying true to Beerus being an asshole god?
Beerus is an incompetent asshole, I think we should acknowledge that part of his character ain't changing, at least not anytime soon. Beerus's asshole character and him not doing his job is how threats like Moro exist, and we know that the writers aren't going to let that trait go as long as it offers Goku and Vegeta foes to fight in the near and distant future. Even if the entire Universe gets fucked due to how these threats are allowed to rampage, as long as our favorite duo get opponents, the series gets to continue.
