I once went on a blind date with a prosecutor from a large city, who worked in a department that investigated corrupt cops, lawyers, politicians and city employees. She said some of them were straight up psycholopaths that needed the book thrown at them. Others who had a singular lapse in judgment and found themselves on the wrong side of the law received some leniency. So penalties like this are to give the judge or jury a tool to remove someone permanently from the position they abuse, or to give them an opportunity to make amends. Or re-offend but second offenses often carry stiffer penalties.
