Clementine is my number one priority and Ben repeatedly fucked up on watching out for her and it was just luck she didn't end up dead. Maybe it'll come back to haunt me, but I let him drop in the bell tower because no way in hell was I risking my own life and my ability to protect Clementine just to save Ben's unreliable ass.
I still feel like Ben is kind of the every man in the series though. If an actual apocalypse I doubt anyone here would be as good and noble as Lee is. We'd all fuck up and Ben never did any of it to hurt anyone. He only tried to help.
