Why God hate some people before he created them

In National Geographic world history has written some religious insanity, and such are unprecedented in the life of moderm intelligent human beings. Charlemagne waged battle in the name of Christianity. "It is our task," he said, with the help of divine goodness to defend the holy church of Christ  everywhere. The church's teachings and practices shaped the lives of Christian Europeans. As representatives of Christ on Earth, medieval popes eventually clamed patal supremacy, or authority over all secular rulers.  The text says:  In the Middle Ages the church's most important  achievement was  to Christianize the divers peoples of Western Europe. In 597, Pope Gregory 1 sent Augustine to convert the Anglo-Saxons in England. The medieval  Church developed its own boday of laws and administered  the sacraments, it had absolute power in religious  power. What is seriously and fatally wrong with this Church establishment, is that  it lacks real precedent, no occasion is cited for where the church got its initiative from, as to where the initial authority  derived.  How can the evil invation of Jews brings or yield us Jesus?  How do they come up with a spirit God that foreknew all things prior to making the creation. How can a God knowingly make man to sin, and beforehand hate and love some people over others?
