Why The Walking Dead Season 5 Was the Bleakest So Far

Father Gabriel is easily one of the most infuriating characters on the show. He's clearly carrying so much guilt for what he's done in order to survive, but it has such a negative impact on everyone else. Over the course of the season, Gabriel continually puts the group in danger; he even unknowingly leads a group of walkers right to them. He also lets walkers into Alexandria (an event which arguably sets the finale's entire chilling final sequence in motion), casts doubt on Rick and the gang in the eyes of Deanna, and almost drives Sasha over the edge.
