I guess my point is she doesn't have any ulterior motives for wanting to take them down. She doesn't want to usurp their power or anything, like our Loki would try to do. She just wants to get rid of them so she and people like her can be free to exist. It's that difference in motive and personality that makes her incompatible with the sacred timeline, because that's not how a Loki is "supposed" to be.
Or so she says! She is a Loki, after all. Maybe we're supposed to fall for it.
