The reason she didn't kill Armin on the battlefield to me is no different with Jean's case, as he was also there together with Armin and Reiner. The difference would be Jean's assault towards Annie that led to his injuries.

Beside that, I think that she harbors feeling for Eren. She is the one who taught Eren how to fight, to the point that Mikasa getting jealous of their interaction and physical contacts as we can see in the new flashback. What could her motive be other than that?
