Varian, with reference to your OP ''Abraham is traditionally considered to be the first Jew and to have made a covenant with God. Because Judaism, Christianity, and Islam all recognize Abraham as their first prophet, they are also called the Abrahamic religions.
So the Jews, Christians and Moslems all believe in an omnipotent deity - the same omnipotent deity fostering good, not evil.
So why do they hate each other enough to kill each other?
And why does this omnipotent God allow it to happen?''
I think the reasons are historical , for instance Paul had a revelation and taught the Gospel to the Gentiles, then Constantine adopted Pauline Christianity for his empire. Christianity and Islam each stemmed from Judaism for historical reasons.
Muhammad needed to modernise the Arabian tribes that depended for social control on intertribal vendettas. Obviously the Judaic deity was a central means of control that needed a little tweaking to suit the god to Muhammad's need for centralised military colonisation of the Mediterranean region and its trade.
Over all three sects the main ethic was the civilising humanitarian ethic as explained predominantly by Jesus.
