You're using hyperbole to make your point as clearly I haven't said things should go unpunished. Corruption is a broad spectrum though, not every single piece of minor corruption should mean lifetime in prison, some obviously should. Maybe for example if you give someone you know a government contract because you've known him for 20 years and he's highly competent and trustworthy, and you're actually using your personal relationship with him in a positive way to serve the interests of the country, someone could view that as corruption even though your intentions were good and you had the best interests of the government at heart - sorry mate lifetime in prison for you.
