Nemnok the Devourer

Is there a reason to defeat Nemnok from the RP perspective for a not-too-aggressive PC? The settlers seem to like the arrangement, as do the people (including the flame naga) working for him.

If Nemnok wasn't the strongest non-dragon boss in PoEII and one of Junvik villagers wasn't unhappy with his son's occupation, would you attack him?

 

Also, I took Nemnok the Petite to visit Arkemyr. No reaction from either of them.

Nah, the imps get enough **** that I figure if one who got lucky ever manages to bring retribution sweeping down from the north it's just karma. 

I can't quite remember why, but he attacked me on site.

 

I don't think I learned enough about the situation, as well, but then again, I don't think I was given enough info, too.
