Can such a thing be truly ascertained? No, not really: Who’s to say attempted cannibalism is worse than developing a crack addiction just for the welfare checks? But with the gleefully depraved FX comedy’s sixth season starting tonight, Vulture parses Sunny’s backlog of horrors in order to determine the one transcendent offense Charlie, Mac, Frank, Dennis, and Sweet Dee have each individually perpetrated. (That’s individually, so the manifold terrible things they’ve done as a group — like, say, accidentally terrorizing a Mexican family — don’t count). Click through to be amusingly horrified! And, as always, let us know what we’ve missed.
