How is Guicciardini a role model?

Guicciardini is the role model for separating personal emotions and thoughts in the conduct of reprehensible business. In I Ricordi Guicciardini states "No man hates the ambition and avarice of priests more than I do; for these vices, odious in themselves, are most unseemly in men who make a profession of living in contact with God... My position under several Popes has compelled me to desire their aggrandizement for the sake of my own profit..." Realism and Guicciardini, Page 162
