First and foremost Regina has done so much और good than he has. Regina spent 2 seasons working at redemption and I think it paid off whereas Rumple is still lying through his teeth to Belle about how he's a changed man as he goes off to murder Zelena...the woman Regina spared and actually kind of saved. Regina's redemption arc has been really successful to this point. Rump's was a joke. Okay he stabbed Pan and saved everyone at the cost of his own life. That was the right thing to do. However he turned around and went for vengeance again, something Neal wouldn't have wanted done in his name....
