No, Morgana was not evil, she allied with Morgause because she was the first one to understand her and accept her with her magic, and she was also magical. If Merlin had ignored the Dragon's warnings and done that on 2x03, Morgana would not need Morgause and the future would have taken a different turn.

As for Aithusa, it is definitely a she because dragons need to reproduce! I agree that she is a complete mystery though.

Well...it's probably in the "growing up" part. I didn't understand Merlin either so I wouldn't know!
