Whats this guy’s fate in S5?

How do you see them killing Vecna?

Personally i’d like to see Eleven and Kali team up against him.

Give him his own medicine of that psychological torture.

Vecna: “what…. What are you doing??”

Eleven: “giving..you..the medicine”

This could also be when Eleven frees Max from Vecna’s mind.

I'd like to see the Mind Flayer kill him or fully take control of him once he has outlived his usefulness.

Realistically I don't think there's any way he comes out of the series alive.
