Who started warfare? 

     It began before Adam and Eve. God created angels for his kingdom. One angel was established above all others, and in Ezekiel chapter 28 God tells the prideful angel, and us, what happened: 

In the pride of your heart you say, I am a god. I sit on the throne. 

Though you are not a god, you think you are as wise as a god.

You will die a violent death. 

You will be but a man, not a god, in the hands of those who slay you.

You will die the death of the uncircumcised at the hands of foreigners.

You were a model of perfection, full of wisdom and perfect in beauty. 

Your heart became proud, and you corrupted your wisdom.

You were anointed as a guardian cherub, for so I ordained you. 

You were blameless in your ways till wickedness was found in you. 

Through your widespread trade you were filled with violence. 

So, I threw you to the earth. I made a spectacle of you before kings.
