Conservatives take the “tragic view” of human nature – that humans are inherently fallible and corrupt, and so we need structure in our society to reign in our darker impulses. Did the Founders share this view? Well, at least some of them did. From The Federalist Papers:
Why has government been instituted at all? Because the passions of men will not conform to the dictates of reason and justice without constraint. Has it been found that bodies of men act with more rectitude or greater disinterestedness than individuals? The contrary of this has been inferred
by all accurate observers of the conduct of mankind; and the inference is founded upon obvious reasons. Regard to reputation has a less active influence when the infamy of a bad action is to be divided among a number than when it is to fall singly upon one.
-Hamilton, Number 15
