The ultimate act of love beside Christ dying on the cross for the sins of a otherwise sinful race was to establish death in the first place. In God’s secret will, he ordained that, rather than showing love by allowing us to continue living in sin without perishing, we would be killed for it. For us to have continued living on this earth with the knowledge of sin and willful desire for it would have caused a nightmare for earth. It was love that established the curse of a bodily death.

So to address what possibly Rod was trying to get at would be along these lines: to end life as the result of self-defense or protection against “Jack” through the use of a bullet is in many ways is a grace of his life. He cannot continue in sin; though he is bound for hell, he will only answer to what his life as shown to that point. As it is an act of love for God to establish the life-cycle for his own sinful likeness’s, it is also an act of love to prevent a man from continuing to sin and abound in it. Christ kills our spirit in regeneration by his own sacrifice, thereby renewing it and making it new through this process. What is left, as the scripture says, is our body, our “flesh”, to finally die.

Maybe this helps you understand what he maybe was trying to point at.
