A few points here:

1. HFCS is more fructose (not by much, but enough) and it is the fructose that is bad for you. The sugar is also bad. They are BOTH bad.
2. Fructose inhibits the body's ability to know that it is full so you eat more calories
3. Fructose is mostly metabolized by the liver, other sugars are metabolized by all the cells in the body

There's no valid argument that says that sugar is anything more than nominally better than HFCS. THEY ARE BOTH BAD when used out of moderation.

It is easier than you think... If souls exist, it is a religious issue. And most religions state that God owns your soul, not you. It isn't yours to sell. Contract invalid. If they don't exist, there is nothing to sell. Contract invalid. Even if you come to the point that the soul is something that is yours, there is no way for one to collect on such a deal. Thus... you guessed it... contract invalid.
