American soldiers were criminals in that war. This is a fact.
Any normal person will not go to Iraq for the second time.
He just liked to kill with impunity.
No they weren't. However, the islamist terrorists who targeted civilians and american troops, the ones who Kyle killed, were certainly criminals by any convention of war.
I don't know what you mean by normal. Yes it is pretty extraordinary, an average person wouldn't sign up, much less go back, but this isn't a mark against his character but a sign of his courage and sense of duty. I don't agree with the war myself but I admire his commitment to protect his fellow soldiers. It is also admirable how he continued his service to his fellow soldiers when he left the service, helping them overcome ptsd. Even if I don't agree with his view on the war, he was a good man for doing this.
"The United States had no authority, legal or moral, to attack, invade, and occupy Iraq. No nation has the authority to attack another nation and kill people in the process. The fact that the U.S. government has the most powerful army in history and that Iraq was just a Third World nation makes the situation even worse.
Since the U.S. government was the aggressor in the war on Iraq, that means that no U.S. soldier had the moral authority to kill even one single Iraqi. Every single soldier who killed an Iraqi or who even participated in the enterprise was guilty of murder in a moral, religious, and spiritual sense."
Any normal person should feel guilty about it. Chris Kyle did not feel it.
He is a murderer. He is not a man.
