God, Why Did You Do that?

With all the talk about whether or not God exists, I have been thinking. If he/she/it is real then why is there war? Why are there mentally/physically challenged people? The existence of something above us is quite mindblowing. It does call into question on whether God is a person, whether he/she/it is with or without human qualities, is there a beard or sandals, and many more just like in class. I just thought I would bring up the fact that there are imperfect people in the world. They bring up another question. If God made us in his/her/its image, why then are there people who are handicapped or power hungry and what does it say about God's image?
