This Post Now Belongs to Negan.
Negan was originally a member of the Hilltop Community before he found some people to create the Sanctuary.
Lucille "The Vampire Bat" is named for he dead wife. She died of cancer at the beginning of the apocalypse.
Negan has the fifth highest kill rate at ~30. The governor has the highest at 139. Rick is at ~55.
Negan's story arc was supposed to be fairly short in the comics. However, Robert Kirkman loves his creation, and keeps him around.
Even tough Rick and Negan are parallels in many ways there is one important difference, their motivations. While Rick's behavior can be out of line, he does it to protect those he cares about. Negan's motivation is personal gain and power over his followers.
