I had an old buddy who served in Vietnam. One time I asked him what it was like to kill someone. I’ll never forget his answer.

“You know, when you’ve got your rifle trained on somebody, there for a split second you’ve got the power of God in your hands. You get to decide if that person lives or dies. Nobody should have that kind of power. I only wish I had known that before I had done things that I couldn’t undo.”

He said he still had nightmares all the time, even 45 years later.
