Except were not dealing with logical/rational people. Nutty-Netty, Ben Gvir, Smotrich, etc in that war-party that controls Israel, are all about killing because they take all of those silly stories and nonsense of the Old Testament seriously. Just like their role model Zealots and Sicari from the Old Testament did. Their god tells them to kill and "save alive nothing that breathes".
When the Lord your God brings you into the land you are to possess and drives out the many nations larger and stronger than you, and when the Lord your God has delivered them over to you and you have defeated them, then you must destroy them totally. Make no treaty with them, and show them no mercy. Do not save alive anything that breathes…Do not intermarry with them…Do not give your daughters to their sons or take their daughters for your sons…Break down their altars, smash their sacred stones and burn their idols in the fire, for you are a people holy to the Lord your God who has chosen you out of all the peoples on the face of the earth to be his people, his treasured possession…’–Book of Deuteronomy
