“If Rumpel just wants the curse broken then why did he help Regina to do the curse in the first place?” That is the essential question the OUAT creators Kitsis and Horowitz want us to ponder.
Kitsis also brought up the idea that the whole curse may have been designed to benefit Rumplestiltskin and not the Evil Queen. “Why would somebody create a curse that they didn’t themselves employ and for what reason?” Kitsis asked.
“That is a question we’re going to answer this year.” Robert Carlyle added when talking to TVLine. “You realize that maybe Rumplestiltskin [didn’t create the curse] for her at all. Maybe he was doing it for himself.”
Which brings up the biggest question in all of this: What benefit could come to Mr. Gold in the cursed world of Storybrooke?
