I feel like he will become a host to Vecna

Mileven happens but Will doesn't get depressed because he's already dead

A "well-deserved villain arc"?! What are you talking about?!

@Whitehorse24 Some people think that Will deserves a villain-arc such as teaming up with Vecna to counter all of the mistreatment and trauma he has faced as a child and growing up. There has also been MULTIPLE parallels of Henry Creel and Will... While I wouldn't be completely against the idea if it were to happen... the chances of him having a full-on villian arc is low (I can see him getting possessed by Vecna tho... especially after the season 5 teaser)

Well, I hope he doesn't get one as well, "heroes turning evil" can be terrifying! On a show like this, the chances of someone fainting upon seeing the actions of an Evil Will Byers are pretty high if you ask me.
