I don't know but since Negan is the most evil, sadistic, psychopathic murdering basturd I've ever witnessed on TV, I hope the writers surpass Negan's over the top brain bashing in this past season's opener and create an even worse scenario for his demise.
Maybe a 15 minute segment of breaking every bone in his body from the waist up then cutting off his hands and applying tourniquets so he doesn't bleed to death and releasing him in a pen of walkers after gouging out one of his eyes and ripping out his tongue.......
I deliberately refrained from breaking his legs so that he at least had the ability to try to evade the walkers with his remaining eye..........
Or, he could get the comic end, which is a fate worse than death, for someone like him.
