..see I have to say that I didn't like the movie that much..a appreciate how changed he was in life and why and the ironic way of his death and how sad etc...I guess that I just don't generally like movies of war torn countries where such a strong psychological perspective is put on one particular 'side'..I know that has to be I guess but I just don't like it personally..even from the opening scene when he was on the rooftop and his rifle was aimed at a small child who was suspected of having a bomb...the child was still old enough and as it was part of his daily life type thing...to have awareness of what he was doing and that he also would die in doing it and I just found it frustrating to not have a perspective of a child doing that and also of his parents/family etc who would have sacrificed their child who they loved...anyway I'm not sure exactly if I can explain why I generally am less keen on these movies but they're just something that disturb me quite a bit and I can't ever say that I like them...obviously with this it's a true story and a sad one and he wasn't someone that I was aware of so it was interesting watching it...I think that I might try the book now that you have said that their are huge differences...
