Merlin is very suicidal! He's tried to give up his life for people like a hundred times! He drank poison, he ran into a dorocha, he left himself to the mercy of bandits etc etc etc!

If Merlin did put a dagger to his throat, it would be because he was testing to see if Arthur really wanted him dead, and to also prove to Arthur that he would do anythinng for him. He isnt afraid of death, he's got all those people waiting for him in Avalon (yeh thats a bit goth i know). What he is afraid of is that everything he'd done will be for nothing, and I think if Arthur told Merlin to kill himself because he didn't care and he still though magic was evil, Merlin would want to die. (NOTE Merlin's suicidal tendencies started in episode one, "If I can't use magic... I might as well die."
