"Good Night, Willie Lee, I'll See You In The Morning"

I think that if the killing is unfinished business then they would mean that the son and mother would die also. I think when the poems says that, "The healing of all our wounds is forgiveness that permits a promise of our return at the end", that this means the victims healing and spirits being sent above is forgiveness but it is a promise that the killer will receive his treat at the end of the whole situation. The unfinished business in my personal thoughts in this poem was the killers getting there punishment for what they did or the killing of the whole family. I have more thought that it is the killers getting there treatment because the person or people that participated in the killing are not going to walk away free.
