I agree, the relationship between Merlin and Morgana is one of the most interesting and tragic ones of the show, compared to how they used to be in season 1 and 2. However yes, I think that Merlin was really going to kill her, if it weren't for Morgause. Of course, no matter how both try to kill each other, it just can't happen, since they're both the main heroes (along with Arthur and Guinevere). However I don't know what to expect of his actions. As you said, it's unpredictable since they don't get so many scenes together.
