Sorry but this still doesn’t quite scan for me.
From this moment with Beowulf until the moment Bae leaves the EF, he is living inside Rumple’s house with the dagger, which apparently can exert some measure of influence on non-DO’s. He’s still a “hormonal” teenager with all those emotions of anger, sadness, pity, resentment and fear and moreover he’s watching Rumple get worse and worse, actually going out of his way to main and kill people–the maid, the snail man. But at no point does Baelfire take the dagger and order his father to stop or anything with the dagger. Because that’s who Bae was; he did not recklessly give into dark magic either because it was easy or because of some sort of influence from the One Ring (I mean Dagger)
