Because she wants to pretend to herself that she can make up for her stupid blunder in the Season 3 finale by setting Zelena up to be murdered in cold blood. That.... and because Emma multipied the Darkness, and now needs to make a human sacrifice.

Also, it is very possible that the entire town was marked for death. Which explains the fury's arrival for Robin, and then Emma's plan to murder Zelena. Both plans failed, and now Nimue is in Storybrooke to collect the souls. The Dark Swan said, in 5.02, that there was a problem heading to Storybrooke that only a savior could solve. She was probably referring to Nimue, not the fury. So, Hook could be playing along with Nimue, to force Emma into using him as the sacrifice. After all, he was destined to die back in Camelot.
