We may very well will to do something that is antagonistic to our nature - that is, free from the self - but never something entirely removed from our humanity, the shackles of our mind and soul. Even death - as we have come here to seek it - is not a completely free will, but rather that, while it is contrary to our innate survival instinct (and, thus, free from our humanity), the decision to desire it is one that has been arrived at by a complex route in which each of our mind's vices are a station.
