I agree with you..

Like you, I also think that him caring about Arthur and not wanting him to die was one of the many reasons of why he took that decision... it was clear that in that moment when Arthur ask him what he would do, he was dealing with an inner conflict... I mean, he had to choose between save Arthur's life (his best friend life, who he saved many times) or let his destiny come true but knowing that it wouldn't last too long because Mordred would be alive to destroy it.

I think that in some part of the episode Merlin says to Gauis that he likes Mordred too, but cannot trust him, because of what he saw... if he said that he likes Mordred, it must been hard condemn him to death...
