Out of every villain I have ever seen on The Walking Dead, and in TV as a whole, no other villain has quite captivated me like Negan.
Introduced at the end of Season 6, Negan was first seen as this horrible man leading a group of horrible people, who lead some of the saddest Walking Dead deaths.
We start to see that while he is a screwed-up dude, he also has a strange set of morals.
However, over the course of the next two seasons, we start to see several sides of Negan.
