Nonsense, God-fearing muslims slaughtered the Armenians, God-fearing Hebrew tribes slaughtered the Canaanites, God-fearing Spaniards took out entire cultures in the Americas... come on. God-fearing muslims, are in fact slaughtering people briskly at this very moment. You may disagree with their grasp on what “God” wants but you can’t deny they think He’s up there.
But it is God "up there" who commands them to do these things? Maybe they are simply using God as an excuse to perpetrate purely human crimes, to "sugar-coat" acts of purely human libido dominandi and moral turpitude.
Certainly I believe that is the case with Islamic Jihadism.... I also believe that to have been the case WRT the Spanish conquistadors....
The case of Israel is seemingly different. But I would leave the elaboration of that issue to Jewish scholars, not having the competence myself.
