The common sense and what's wrong .

It is commonly known that God is the source of all good.It is commonly known too, that all religions that existed fight against each other just for one purpose. A Truth . Which Truth is fitter than the other to be called a religion ?
We fought and we lost sight of the purpose religion existed . Explanation of existence in itself because we cannot understand it and to establish the good . But we fought .
this world is a plot twist and God can either be Good or Evil.Maybe Evil existed Before anything.Just maybe we should always fight.
