A great and easy headcanon to use is that the dagger corrupts its wielder (which is does, but usually the wielder is the DO). So, Baelfire wouldn't but he had the dagger in his possession and felt he had to do it. I guess we should give Rumple a pass then if it corrupts people, that's not even the Dark One. Honestly, I'm certain we never seen anyone wield the dagger for non-selfish or impulsive reasons (except Merlin for obvious exceptions).
