No one in the right mind desires what is coming at us and what must in turn be done. I’ll wrestle with my conscience later. If I live through this, I’ll ask my Creator for forgiveness. Somehow, I think - I hope - that I’ll be understood.
Should we prevail, our descendants will eventually honor our sacrifices.
If you do it for the right reasons, you’ve got nothing to worry about. I am assuming you have a working conscience by the very fact you’re concerned about it.
