This. Peace cannot come unless the civilians on both sides are loudly and forcefully willing to die rather than kill civilians on the other side. The problems can only be solved on an individual level.

I suggest a different approach in some blog posts I worked through a couple years ago: https://saladeggs.blogspot.com/2021/06/reconstructing-christian-ethics-01.html

In short, I suggest sin is that part of you that drives you to self-destruction and destruction of others, and the actions flowing out of it. Discipleship is the process of becoming a non-destructive person.
