For me, it only makes sense (kind of) if Merlin was too a Dark One at that point. Emma did Hook the same thing Zelena did Merlin. Why did Hook become a Dark One I'll never get. Merlin was not a Dark One, but rather a powerful sorcerer with neutral magic. He chose to use magic for good, and not give into his darkness. Emma corrupted Merlin's magic and immortality, when she used the darkest of magic to steal it. Hook became a Dark One, because of Emma's selfish actions. Emma doomed Hook more than he already was, by giving him a fate worse than death.
