The vote to kick or keep Ben in the group. I absolutely hated his guts for all the suffering that he caused even if it was unintentional. All the characters that I cared about bought the farm due to the chain of events he unleashed on the group. He was a coward too, refusing to help Clem and leading to Chuck to sacrifice himself. I can understand from a rational perspective why Ben is a screw up, but when I try to play in character, I figured being pissed at him made sense and would take priority.
But when it came down to it, I had a much tougher time clicking the abandon Ben option when Clem chimed in "We don't leave friends behind" or something along those lines. Damn you Clem! During my playthrough, I've decided Clem and Carley would be my moral compass. And since Clem obviously objected and I suspected Carley would've too even if she knew what a POS ben was, I decided to vote for keeping.
