I think giving the photo to Stitches is what it was. He's been the only one to show active remorse or cognizance so far. And it's always those strange little acts that make the biggest difference, later. Hopefully for the better.
As for Filbert, consider this; as far as we can tell, dying means you 'bring something back' with you upon resurrection. This means dying MULTIPLE times might make you worse, and worse, until you're a seething mass of chaos and corruption. This is probably why we want Ruby and Tom to avoid death; we may be able to survive, but it would probably also close out any chance of redemption or escape, as we'd be too far corrupt, like Filbert.
Just a guess. But the photo seems like the big action.
