1. Yes I do think that Jefferey Dean Morgan is a good choice. His role as The Comedian from the Movie Watchmen had me convinced that he has the talent to play as Negan.
2. As for the Person who is going to be killed by Negan I don't know for certain, but if there going to take the Comic book route I would be okay with that. but people who have read the comics would see it coming, So I think they will change it up a little bit.
Also As for Season 6 I am planning on adding Some plot elements from Telltale Season 2 The Walking Dead remixed into it, So you can expect some huge things planned for my upcoming Season.
