Forbidden Fruit

Why is it that when you have something good, something lovely and beautiful you sometimes want the very thing that opposes that because it LOOKS good? That "fruit" could look so edible, so healthy, so tasty but what price do you have to pay to bite into it? What do you have to give to live after taking a bit of that fruit? Snow White almost died, Eve and Adam lost their closeness with God, and many others have paid the penalty of tasting that forbidden fruit. So why is it that we, as a people, keep walking towards that which is forbidden? Is the danger that alluring? Does the threat somehow excite us in ways that safety and comfort cannot? Or is it simply the unknown...a way to deviate from "normal" and "predictable." Who knows? I sure as hell don't. I'm just throwing out these questions. Maybe you have some idea?
