How we cite our quotes: (Part.Chapter.Section.Paragraph)
Quote #7
Twenty yards beyond the farm buildings, in a narrow ditch, we came on what we sought: a woman and a small boy. They were very clearly dead: a small neat clot of blood on the woman's forehead, and the child might have been sleeping. He was about six years old and he lay like an embryo in the womb with his little bony knees drawn up. 'Mal chance,' the lieutenant said. He bent down and turned the child over. He was wearing a holy medal round his neck, and I said to myself, 'The juju doesn't work.' There was a gnawed piece of loaf under his body. I thought, 'I hate war.' (1.4.1.46)
The sight of innocents killed, a pious mother and child especially, reinforces Fowler's rejection of God and religion. Such "mal chance" shouldn't exist in a world governed by a benevolent God.
Quote #8
Perhaps to the soldier the civilian is the man who employs him to kill, who includes the guilt of murder in the pay-envelope and escapes responsibility. (1.4.1.47)
Fowler wonders about the perspective of soldiers, who have to live with the memory and consequences of the orders they carry out. That might explain some of the reasoning behind things the Veteran's Day—it sounds like quite the load to bear.
Quote #9
The cannon gave a single burst of tracer, and the sampan blew apart in a shower of sparks: we didn't even wait to see our victims struggling to survive, but climbed and made for home.

I put on my earphones for Captain Trouin to speak to me. He said, 'We will make a little detour. The sunset is wonderful on the calcaire. You must not miss it.' […] and the wounds of murder ceased to bleed. (3.1.4.12-13)
You might think that Greene is judging Captain Trouin for sharing the view of a sunset right after he attacked a populace from the air, but Greene understands why the pilot takes the time. It's a way of coping: "the wounds of murder ceased to bleed." He's holding on to his humanity.
