Maggie or Daryl Kills Him
Before season nine began, I would have completely balked at the thought of Maggie or Daryl being the ones to do Rick in. They're part of the original survivors! They were in the prison together! They've been through it all! But recent events show that neither Maggie or Daryl are playing by the same rules as Rick now, and you never know what they might do if he continues to stand in their way. After all, Maggie is still enraged and grieving over the death of her husband, while Daryl has to face those complicit in his capture and torture every damn day. The relationship between the trio seems ripe for betrayal.
