I am sorry, obviously I misread your OP; I agree with you and Kathryn about this world being a 'test' - especialy in that we are to accept everything 'in Faith'. I think that is the main deal, the other test, which both you and Kathryn have highlighted is the one of being free to choose between good and bad. Apart from man's laws, there is little evidence of any harm in doing 'bad' things; I guess that is just how God wanted it to be - his own 'personality' and purpose totally hidden from us, to make the test as 'good' as it can be.
