Didn't Legion cause the Age of Apocalypse? Kind of not a good role model for identifying with people with emotional disorders. It's like how Carnage was a child abuse / neglect survivor - not exactly good press.

Though as recently discussed here, Peter Parker was confirmed as a CSA survivor too, and to that you can add Karma from New Mutants....
