I don't think he is being too merciful towards her. In "The Crystal Cave" he was right not to kill her, because this time she was not up to something evil, she was only going to her sister on her birthday. In the Servant of two Masters, he was convinced to kill her, but then she spoke his own fears-that Arthur may always keep magic banned in Camelot, and that things will be different with her. In The Sword in the Stone, I think he wanted to, but she was fast enough to teleport out of Camelot. However, even so, we saw that she would have been dead, had not Aithusa saved her, so I believe he is not merciful towards Morgana anymore.
