(Spoilers) At the end when he's lying down....

Amazing film, I was completely captivated from start to finish. I found a few scenes weird, like when she jacks him off, but I sort of get it in the sense that it's made to make you feel uncomfortable, or maybe it's meant to increase the bond between the two (I don't know how lol) or something.

One scene at the end got to me though, when he's digging the grave of his "mother", he finds one of his victims wearing the jumper she was knitting. Wouldn't he realise then that she wasn't his mother and this was revenge for her real son? He must have known that that was his victim because he was in his shop earlier looking closely at a photo of him. And even if he didn't know that was his victim wouldn't he feel different seeing his mother had another son and cared enough for him to knit that jumper and put it on his dead body but not see him for 30 years? Or is it simply that he may have realised that she was not his mother but was already too close too her and so still felt the same pain he'd inflicted on others anyhow? He had changed as a character by this point and so maybe it didn't matter anymore whether she was the mother or not, he suffered the same pain anyway, as well as the fact that he did this to so many people weighing on him?

I'm not too hung about this, it almost seems pointless asking these questions in this kind of movies seeing the way it made me feel, it just got me thinking a little bit though and realised no one else posted about in on the message boards.
