What kind of game can I make that would test people?

I think you need to determine what it is that you want to test first as that would affect the type of game. As for testing morals, that's bit hard since who determines what is considered moral or immoral. What yard stick do you use for that. Baptist think it's a sin or immoral to dance or play cards, Methodist don't. You can question people about their beliefs but here again, it's not really game material.
