Goebbels was a smart, amoral kind of guy all right.
On the theme of religion, I would like to point out that picking a religion is more likely to land you in heaven then none at all, because if you believe atheism then instead of a 1/however many chance you have 0 chance. See pascal's wager.
On Pascal's wager I would say that actually, picking a religion and getting it wrong is more likely to get you into Hell. At least with atheism there is no chance of being tortured for all eternity. Please take a look at the following image for a better understanding of what I mean. [link]
Further I would contend that any person who chose a religion solely on Pascal's wager wouldn't get into heaven anyway. You are certainly not going to fool the gatekeeper of heaven that you genuinely believed.
Why couldn't they choose a different, more accepting and less violent religion to spread around instead of Christianity? Like Buddhism. I don't know about you but i'd take Buddhism over Christianity any day.
