True, true... but consider this: they make that choice over and over again. Every time life asks them that question, they continue to take the deal. They don't smarten up and back out. They can't say no to that one slice of cake, not when it is offered today, not when it is offered tomorrow. They don't learn from their choices, and repeat them over and over again. If anything, it makes them even more idiotic. It's like if you throw a rock at your own house, and break a window. And instead of thinking "oooh, that was stupid I better not do that" you do it again the next day. And the next. And the next. Until your house is smashed to ruin and you cry "house privilege" at your neighbours.
