What on Earth is your point? You agree with my point that punishment is not eternal in Buddhism, and then go on to write about how karma works. Is your assumption that I don't know any of this, and that I need to know in this context?

The people that I mostly have in mind are people that bet on Pascal's Wager. People that are not necessarily Buddhists, or even religious to begin with. From their standpoint, it might not be that crucial to bet on Buddhism, since it they're wrong they won't have to pay for it for ever and ever.

(Gotta say that I was surprised to see M. O'Church talking about Buddism, btw.)
