Nethack: prey, then pray

I’ve started a new game as an orcish barbarian. One thing I’ve run into early on is an altar. Your character can gain benefits from his god by sacrificing his kills on these things. This altar-sacrifice “feature” is shared among many roguelikes, including Dungeon Crawl, frequently cited as the most “user-friendly/modern/fun/not stupid/actually playable” example of the genre. And I wonder if anyone actually likes doing it? It just feels like homework to me. You’re an adventurer exploring a dungeon and thwacking baddies, I get the allure of that. But to then pick up your victims and lug them to an altar for brownie points just feels like taking out your recycling, and it’s about as much fun.
