Why are there so few anime with an evil protagonist and/or plots where the bad guy always wins?

Albedo can be interesting if she started betraying the interest on Nazarick to get the Ainz bone.
She's obviously far from Ainz for long periods which should be driving her crazy. What if she sabotages him in a way that he has to stay with her.

>Overlord was clearly written by that creep who stands on the corner, observing everyone, and cursing why no one ever cares about him
Imagine projecting this hard

I don't see the Supreme Being returning

From the very start it seemed setup as one dude who's still stuck in the same game while all his other friends moved on,some probably together but he himself is unwilling to let go until the very moment because his greatest moments of happiness were with his guild mates. It would probably be awkward if they met because in a way their creation that they left like Albedo and Shalltear and everyone else are like the family Ainz never had and he himself has realised he can't hold his old comrades in his thoughts forever and accepts his new family.

And it is an MMO so Ainz probably has some polymorph potion lying around that can turn him human for a brief moment. But that's just head-canon.

Why are nips so fucking retarded they prefer an oppressive office job environment (that made him start writing in the first place) to continuing his successful franchise. Even if hes just tired of overlord why not just do spin offs or start a new fantasy thing where he doesnt write himself into corners

>>hard NTR
>Ainz suddenly develops romantic feelings for Albedo despite no dingus
>She reverts back to her old settings
>She still reciprocates his feelings but it isnt enough frkn stopping her sleeping around
>Ainz leaves Nazarick and starts exploring the NW while making friends along the way

Because it originally started as a DnD campaign with his buddies who helped him build the world together. Imagine coming to a point years later when everybody stopping playing and the only person who's left is you

But also he's just a prick IRL..

His DnD campaign stopped before he started writing, the whole reason he started writing was bc everyone had left.
