I don't think anyone could dispute that if all humans sinned even 50 percent less the world would be a much better place to live and raise children. If everyone obeyed the Ten Commandments alone the world would be a much better place to live and raise children.
The Muslims thought that the Chrsitians would be easier to convert if they forced them to use allah. Most of the Christians use allah the Father, allah the Son, etc. so they can make a difference between our God and the one of the quran.
