If we and this world were indeed created by an almighty "god" then "he" could not have created insanity. According to christians, we were all created with free will and that is the reason that there is violence and suffering in the world. However, insane people do not necessarily have free will. The reasoning behind this "free will" is flawed as some people do not have it all of the time. Why would "god" "create" insanity?
