[Spoilers] Sir Harry Pearce

[Beatriz]

I agree with Harry's finding his decisions harder, but I think Ruth's return has something to do with it. Harry's being more emotional. I think he wants to be a better person when she's around (I'm not saying he's not a good person without Ruth), well this has been discussed before - Ruthless Harry.

And another reason could be that he's a bit tired of taking those decisions which imply people dying.
