I think Rumple will realize he is a waste of a human being and that he makes miserable everyone he loves (Bae, Belle, Milah, Gideon)

So, I hope he'll go travel in time and he will kill either young Malcom or Black Fairy so he will never be born

If this happens at the end of season 6, that would set things up for the rumored "reboot" in Season 7. It has been said that fate is a powerful force. So, we would see how fate would bring together Regina/Robin, Snow/Charming and Emma/Hook without Rumple interfering in the storyline.

(I know this would mean no Henry. So, they probably won't do it. But Rumple could back in time and kill himself with the dagger AFTER Baelfire left the EF.)
