No. N-O, no. I think the Nether used to be a place like he'll, but in 1.16, it came to life with its new mobs and biomes, I think it is hellish enough with all of that.
There is trapped souls in soul sand. The ghasts could be ghosts. The wither skeletons are basically demons. Herobrine is the devil, and the wither is like the devil's moster or something like that.
I think also the Nether is sort of a world for pigs, I thought of a scenario where Herobrine was sentenced to the void, and when he was the pigs came and took over the Nether and planted forests out of mushrooms and stuff.
Anyhow, adding demons I think is not a good idea.
Cheers!
