I regard anyone who would presume to decide for others what is moral and immoral as a theologian.
Did you mean to say "philosopher" or are you saying there can be no morality without religion?
Yes to no objective morality without religion. There is a subjective morality that is a function of individual feelings. I don't know if that counts as morality in your view.
I'll get back to you on the next part. It is difficult to come up with an adequate definition of weak vs. strong state. A helpful, easy-to-read book here is "Why Nations Fail" by Acemoglu and Robinson. They claim far too much in my opinion, but it is a good book nonetheless.
