As for Aithusa, I dont think he is evil, he probably saved her because he either did not know who she really was (he is only a baby) or even sensed some good in her, healing her to give a chance of redemption to her. Anyway, I didn't really like that twist but the real reason will definately be revealed in Series 5.
