1009. Genesis 9:6. "Those shedding the blood of a person in a person will have their own blood shed, because [blood] has made humankind into God's image."
Shedding the blood of a person in a person means obliterating charity; within a person means as it exists with us. Will have their own blood shed symbolizes their damnation. Because [blood] has made humankind into God's image symbolizes charity, which is God's image.
