honestly if Nurgle were real i'd give Nurgleism a serious consideration. Yeah you're eaten to death by millions of the most pestilent plagues imaginable, literally rotten in every aspect of body and being, BUT

It doesn't kill you and it doesn't hurt and Nurgle seems like a p. good guy when you don't factor in the ever spreading hellplague

Like Grandfather Nurgle seems like a kinder god than the Abrahamic one, imo

(P.s. I really like characters like Nurgle, like he's evil but he's not at the same time, idk, it's a bit more complex than if he just wanted to kill everyone with disease and that makes it interesting.

Same reason I like Stagnate, the God of Undeath in the anime The Faraway Paladin, like, she's "evil" because everything she does perverts the very fabric of reality by upending the natural cycle of life and death, but she's doing what she does because she genuinely cares for people, especially heroes, and wants to both give the opportunity to defy an unjust death as well as preserve the thing she finds most beautiful- a truly heroic soul. LOVE IT.)
