Why is Blood Sacrifice Associated with the Devil

The Devil is not God and will never be God, that doesn’t mean that the devil could not have control over a world or a city or even a group of people. Well simply if God is good and the universe is good then and God created the universe therefore all of the people who believe in and worship God are good. For the Devil to take control he would need to find a away to control people and get rid of Gods people. So the easiest way to do that is to have your followers who are deprived in this world try and kill the good people of this world who don’t worry, and about worship the Devil. In return this is is called blood sacrifice for the Devil because the followers of the Devil are doing this for “their God” and for society and the laws to be created based on their God who is the Devil.
