Circumstances cause us to act the way we do. We should always bear this in mind before judging the actions of others. I realized this from the start during World War II.
I don't believe in war as a solution to any kind of conflict, nor do I believe in heroism on the battlefield because I have never seen any.
Those who have experienced the most, have suffered so much that they have ceased to hate. Hate is more for those with a slightly guilty conscience, and who by chewing on old hate in times of peace wish to demonstrate how great they were during the war.
