Is it really always rude not to bury corpses? Sometimes i'm farming a particular mob (wolves in wolf cave recently, snails or fire spiders in eltibule) and i bury those, but other mobs in the area are just an annoyance (bersekers, mantises/cultists) which i would leave unburied (although i would ask in nearby if someone else was around whether they want those mobs buried).

For me, communciation is the key. Every scenario is different.
