When I was 19 and working construction, I was fortunate enough to hear one ex-convict tell another ex-convict that very thing. The one asked the other why he killed that man at the bar? The other one said, "he needed killing." Because of my sheltered upbringing I was scandalized at the time. But the truth will set you free, as they say.
In my introspection through the years, I have thought of the various reasons and circumstances that I could take a life. Protect my wife, daughter, granddaughter or even any other human being. The older I get the more clarity there is.
Guadalcanal diary, Marietta, or both?
