She doesn't spend every appearance possessed. She and Alex help during the Proteus story, and their life away from the team includes studying geophysics in New Mexico.
That's worth remembering because there's an actual person here with interests beyond Alex and the X-Men. She's trying to do something with her life.
But the Marauders material takes that away again. Malice gets hold of her, and suddenly Lorna is leading people who have already slaughtered the Morlocks.
Using Lorna that way makes the fight more personal. The danger isn't some stranger in a new costume. It's somebody the X-Men know, somebody Alex loves, using familiar powers against them.
And calling that Lorna turning evil misses the situation completely. Malice is using her. The people fighting her have to deal with what her body is doing without pretending that she's freely chosen any of it.
