Every good or brave thing Morgana did she did for someone she cared for. Other people have a strong impact on her, both positive and negative. In most cases, it would lead to a situation where Morgana would have to choose between Morgause and someone from Camelot. If she loses all her memory, Uther and Arthur are the most possible, if not, then it's probably Merlin.

(If you think of it, not telling Morgana about his magic, but still helping, should have showed her that "muggles" would accept her, that she could trust Gwen or Arthur).

There is that thing: http://themomentyouarefree.tumblr.com/post/59152186543/evidence-that-morgana-loved-merlin-the-entire-series. Maybe loving Merlin is to much, but it proves that they were close. If he tells Morgana about his magic it could be enough.
