Cyclops killed a man who at best morally ambigious. The majority of the people that died on panel as a result of Wanda's actions were children. Those kids were far more innocent than Xavier so their deaths matter more to me even if they were minor characters. Also Wanda's crimes happened as a result of her decisions, Scott's as a result of a screw up by Tony Stark. Big differences here. I find it very annoying when people try and make out others are prejudiced when they disagree with them.
