POSSIBLE SPOILERS for anyone who still hasn't finished season 1
Personally I think Ben tried his best in season 1, but just simply failed. At the same time though, he could definitely be looked at as a detriment to the group. He froze when he should have been taking action, and now that I think, i'm not sure he killed a single walker when he needed too. But he was also probably one of the most complex and likeable characters even with him being the "dumbass" of the group. What do you think about Ben?
