Do I sin because of Adam?

[Esquilax]

So, you ignored the main point of my post (how are you defining "natural") to pick on this?
So if I argue that because some animals in nature drown, drowning is natural, what definition of natural would you use to refute that?

I believe I did when I said purposeful or accidental, one is self inflicted thus going against the natural desire to live, accidental should need no explanation of being unnatural.

I don't think you can classify natural or unnatural along lines of conscious desires, because there are plenty of things in nature that don't have them. This is really an argument parallel to the issue it's purporting to be about.
