The problem is everyone seems to think either Sica is the devil, or that SM/SNSD is the devil when the situation probably isn't that black&white. I'll agree with delulu up there and say no, it doesn't make sense for SM/SNSD to kick Sica out after 10 years for no "justifiable reason". They had some reason to risk their $$$/image or it wouldn't have happened. It's reasonable to believe Jessica was instigating tension bts and the girls felt that whatever she was doing would hurt their image more than kicking her out would, because if nothing else, SNSD seems to genuinely care about their success as a group.
