"The Man He Killed"

This poem deals with the struggle of a man having to kill another man because he is a soldier in a war. He describes in the begging "We should have sat us down to wet Right many a nipperkin!" The Man He Killed",Thomas Hardy. This described what would happen in a normal setting outside of war if they were to have met in a bar and just started talking, maybe shared a beer/drink together. War is a tragic ordeal and even though a solider goes into war knowing what his duties are they never really understand the reason for taking another mans life. In the ordinary world things are so different and once a soldier comes back into the normal world it is sometimes very hard for them to adapt again. They might become off guard and think someone is watching them? Become very nervous if approached by a stranger and question why they are talking to them? Kind of like childbirth woman have post-partum depression and in a soldiers eyes he could have this same kind of thing with coming back into the real world and not really understanding the purpose.
