Definitely, it bothered me enough last season when Damon still considered it acceptable to go on a killing spree after Elena breaks up with him, I could really do without another character snapping necks to make a point. I could tolerate it more with Damon in the first season when he was being presented more as a villain, but it seems like the characters are never truly allowed to grow and develop, we're supposed to just shrug off those murderous tendencies as character quirks :(
