He probably saw what a psycho he was...and figured he could take it for the team and save them. I bet if he pointed to someone else..he would have sacrificed himself anyway.Was anyone else wondering why Abraham didn't bum rush Negan when it was apparent he was going to get kissed by Lucille?
I realize it wasn't in the script but in real life Abraham is a big dude and could have at least got Negan in a compromising position.
