It wasn’t until Uncanny X-Men #150 in 1981 that we learned the source of Magneto’s pain and rage. After a terrorist attack against a Soviet sub, Magneto nearly kills the teenage Kitty Pryde.

The X-Men always had a hard enough time trying to combat Magneto as a unit. To even think of trying to fight Magneto off in a one-on-one scenario is practically a suicide mission.
