CMV: Soldiers who commit atrocities in war should not get to return to civilian life and complain about their PTSD.

I have been reading a book on PTSD for college where an American soldier who had participated in the Vietnam war described his experience. He lost half of his platoon during an ambush while they were tracking fighters through the jungle. The next day, he led soldiers to a nearby civilian village and killed every single person there -- men, women, and children. The soldier personally killed several toddlers and babies and he described brutally raping the women before killing them too.

The soldier returned to his home town after the war and continued his life. The focus of the book was on the anger issues and trauma the soldier had. Apparently, he had nightmares of the cries of the women he raped and he sometimes saw the faces of the children he murdered when he looked at his own kids. After some years, the soldier started meeting a therapist and the book then discusses how he started to heal.

My issue is that I don't think he deserves to heal from this trauma. He should be haunted by the horror of what he has done. He has not paid for his crimes. He is not worthy of the help and resources spent on him.  

The therapist and the author of the book clearly disagree with my assessment. Tell me why I should think otherwise.

Edit: I will be back in a few hours to continue the discussion and reply to the other comments.

I personally would argue that he should pay for his crimes. Anyone who commits atrocities like that should pay for their crimes but rehabilitation and reintroduction into society is critical for the betterment of society. People with PTSD often times lash out and cause more violence and pain to their loved ones and others. 

Rehabilitation allows them to become productive citizens who treat others well and make a positive contribution to society. If he doesn’t seek help, then while he continues to hurt, he will hurt others in various ways.
