i jo to that scene sometimes. same thought. guy looking at chest can't believe that small hole was ending it for him. other scene for me is an injection of something straight into his heart. his disbelieve that a small amount of liquid and the tiny hole in his chest is ending him. he looks at it and asks what happens now. told he should lie down because his heart would fail in a couple of minutes. he doesn't believe it because he feels fine. then when he feels his heart failing, he panics. starts beating his chest hoping it will keep beating. a last thump and he gasps for breath but no use as he dies
