I believe everything Rumple has done has been calculated including his capture (as mentioned above).He created the curse, knows how it works, why it works, and how to break it. I also believe he knows what happens to the person who enacted it when the curse does break. That’s why I think he gave the curse to the EQ to enact: 1. first what it entails to enact it (killing what you love most) and Rumple couldn’t do that. He would never sacrifice Bael (or Belle). and 2. what happens as the curse breaks. I agree that he wants personal release and redemption. Can’t wait to see how this all plays out!
