The happy ending is murdering him. That's it. Period.

So true, though i'm sure MC would have to also fight the hounds if he did end up killing the ML... at least i hope MC ends up running away or something, this is horrible

I think he will end up killing his own hounds. As long as they don't end up together even if he just ran away with the children I'm fine with it. It's just too much for him handle by himself.
