Coming from someone with a Magneto Was Right avatar I would have thought you would have been able to dilenate between saying Lorna isn't a Xavierite (hell Lorna was one of the first people in the comics to use that phrase that Magneto had been right) to saying she is bad.
Of course I fully recognize the next writer to deal with her might write her as a Xavierite as opinions about about her willingness to use lethal force as shown on this thread widely vary to an extreme degree. It's no different when it comes to writers.
Lorna herself goes from being written as unwilling to use force even to save her life in RAFOTSE to blowing up Shi'ar starships left and right and trying to kill the IG and Vulcan. Two philosophically completely different versions of Lorna from one series to the next.
Magneto tends for the most part to be the polar opposite of Charles Xavier's philosophical views? Is saying that attacking the character? No, because only an child's storybook Disney philosophy ascribes to big moral decisions in things like war as easy and black and white. I prefer Lorna to not view the world as a generic old time black and white super hero something she didn't even originate on the comics in the 60s as.
As Disney becomes more and more hands on I expect things to increasingly become more and more black and white with time anyway. Tons of comics made early to mid last decade would have never been made in the current era. If they become more hands on with time expect a more clear dilatation between what 'heroes' do and what 'villains' do with less and less shades of grey.
