He did kill that girl who was spying for his..I can't recall her name.Was that necessary ?

He did kill ovelia. True, she did try to kill him but he could have avoided killing her and found a way to exile her.

We don't know who/what comes after Delita.
I think war again most likely.There won't be a clear heir to the throne.Most likely a bunch of children Delita sired with concubines.
They'll fight over the succession and the country will be back where it was before.
