Quote 7
When Evans was killed, just before the Armistice, in Italy, Septimus, far from showing any emotion or recognising that here was the end of a friendship, congratulated himself upon feeling very little and very reasonably. The War had taught him. (4.89)
Having survived horrible trench warfare, Evans dies at the very end of it. Unable to cope with the emotion, Septimus goes completely numb and is proud for doing so.

"The War?" the patient asked. The European War – that little shindy of schoolboys with gunpowder? Had he served with distinction? He really forgot. In the War itself he had failed. (4.113)
When Septimus thinks back to the war, he no longer considers it a grand and patriotic event. In spite of his bravery, he believes the war was a foolish child’s game.
Quote 9
Look! Her wedding ring slipped – she had grown so thin. It was she who suffered – but she had nobody to tell. (1.66)
Septimus is too far gone to really be concerned with his wife. He can’t handle the fact that his madness causes her to suffer, too. Her suffering is, of course, just another sign that everyone was affected by the war, not just those fighting in it.
