[Marvel DC] What is the most disturbing thing a Hero has done while still acting as a Hero ?
gpt
Professor X has a long history of moral ambiguity.

He was infatuated with a young Jean Grey while she was both his student & a teenager.

He enslaved a sentient artificial intelligence to help train his X-Men & kept it's existence a secret.

He hastily assembled a makeshift team of new X-Men to rescue the original team. They all died. One of them was Cyclops' youngest brother.

Xavier then mindwiped Scott to forget the brother ever existed so he'd stop grieving & get back to work leading another makeshift rescue team on exactly the same mission.
