In fact, Kha-Beleth still had a choice if he wanted to escape completely.
That was to return to Sheogh in soul form!
As long as he could return to Sheogh, with the help of the imprisoned demon lords, he might be able to reconstruct his body and complete his resurrection.
But the problem was, what kind of place was Sheogh? Although it was nominally the headquarters of the demons in this world, the real situation was that it was a full-fledged prison. Think about it. A group of demon lords who could easily destroy a country could only sit in a small place with grievances. There were no entertainment activities such as playing cards, Hearthstone, and the like, so they could only stare at each other every day.
Anyone would go crazy after staying for a thousand years, right?
So after finally coming out, he no longer had the thought of 'returning to Sheogh'…
