Which religion would you choose if you had a country you wanted to run properly?

Morality is a system of rules designed to keep a group in existence and apart from others. 

Religious groups are the most powerful groups in the world.  

If we have moral agency, we should ask ourselves which religion we would choose if 

1)  we were orphans without parents and family to offend by rejecting their religion 

2) had a country we wanted to run well. 

Which religion would you choose from the five world religion ie Judaism, Christianity, Islam, Hinduism and Buddhism?
