As a former Christian, I already know all about the church divisions, another reason to want to walk away from it all. But that aside, the biggest problem is this idea, "god has chosen to create a world where he damns people." I don't agree with that. I would sooner lean towards universalism than take that view. Or better yet, just throw Christianity entirely in the trash since its god is a wicked being. 
I have no doubt the true God is loving and good. But if this is Christianity's view of god, then I have no doubt Christians have got the wrong god. The character of their god is more like that of the one Christians refer to as the devil. And yes he is very real, that much I know. Christianity is essentially a form of Islam, aside from the Jesus part. A religion created by an evil, malevolent being who causes and creates wars, evil and wants to damn as many people possible as it can, who predestines or plans, every rape, murder and evil thought.
