The main reason you would corrupt the centaur village is for demon Ahmri at your wayfort, while having Arona lose her fight gives you her beserker set. Also iirc they lock you out of village content for Ahmri and warcamp harem content for Arona
As in jumping argoth immediately meaning she gets disqualified or just not getting involved? Not getting involved removes her and the orc camp from the game (somehow grettel and solveig still make it to the marches, no clue how) I've done it once for roleplay reasons but there's no particular benefit to it. Getting her disqualified is what Wicked_Corruption is decribing
Correct me if I'm wrong but corruption content seems to have been majorly abandoned. So there's no point to engage with it, if it never gets followed up on.
The game does seem to have sidelined corruption content in recent years, sure, but some of it has (to a lesser degree, but still) recived follow ups on most recent events/updates
