I don't believe that Aithusa is evil he hasn't appeared enough on the show or more to the point done anything signifcant to justify him as becoming evil. I mean Merlin saved Morgana during Series 3 after he nearly killed her and he's not evil. So having the young dragon saving Morgana doesn't make him evil.
