Words are easy. Actions are harder. 🙂 He himself stated that magic is like a crutch–he cannot resist using it. He enjoys using it. We’ve seen Regina struggle–Rumpelstiltskin will probably do so, also. 🙂
And again, no remorse for anything that he has done. I will give Regina this–she seems to be giving more of the effort–going to Archie is a start. I have yet to see Rumpelstitltskin actually suffer for his actions or truly try to change.
Plus, when Baelfire hears wha he did t everyone, I doubt he will happy with what his father has done.
