Why would what we call "misfortune" be in any way misfortunate for them?
I don't see a problem here. Why would an evil god continue to do evil? Because it's who they are. Because they like it. Because it's what they do. Similarly, misfortune is in the eye of the beholder.
Additionally, we're talking about gods. They're essentially not (in your case: yet?) human, and don't see human categories, emotions, ideologies, morals and whathaveyou through our eyes, but through a consciousness that's essentially timeless, and - if at all - dictated by completely different and potentially unfathomable concepts.
To answer your titular question: we can't know for sure, but the fabric of life and the universe might depend on it.
