I think Merlin has definitely become a more suspicious character this series- but can we blame him? It's his destiny to help Arthur unite Albion, and he has been warned by countless people that Mordred cannot be trusted. Delving once more into the 'fate' theme, he wouldn't have known that his actions actually inadvertently caused the fate he has been fighting. I agree with you on the Mordred point, but I think that he and Merlin/Arthur were obviously seeing two different scenes. Mordred, I am certain, would not have done what he did if he had seen Kara refuse her chance, and in turn would also not have done it if Arthur had agreed to give her a second chance at first. I don't really blame either side for this- both were really controlled by their fates, but I have to admit that I do blame Kara: as you say, consumed by revenge, whether for a reason or not, she has brought about the fate by going about her revenge in the wrong way; killing innocents.
