(In)Decision

I've frequently been troubled (philosophically, not emotionally, speaking) by the concept of Free Will. In considering this issue, I've been reading a book called "Indecision". In this book he makes a remarkable question when faced with the issue of his own paralyzing indecision and true nature:
"When we realize we are an animal, how do we keep from becoming a vegetable?"
The flip side to that, of course, is the "abuse" of free will that results in licentiousness or general pursuit of self-interest at the expense of responsibility. (See Romans 1) But I don’t believe that the latter option necessarily supports the position that Free Will is all evil, although some would argue that point especially on a soteriological perspective.
The Clash and the Apostle Paul have something in common after all, this decision/indecision paradox.
Clash: Should I stay or should I go now? If I go there will be troubleAn’ if I stay it will be doubleSo come on and let me knowThis indecision’s bugging me
Paul (Romans 7:18b-20, NET) For I want to do the good, but I cannot do it. For I do not do the good I want, but I do the very evil I do not want! Now if I do what I do not want, it is no longer me doing it but sin that lives in me.
Conclusion? I don't know.
