Dante delineated a hierarchy of sins that, as a Thomist, he based on human reason. Thus the worst sins were lying, deceit, and treachery—the use of the intellect to subvert the truth rather than to disclose it. Those guilty of such sins, especially Judas, were trapped in ice in the lowest depths of Hell, because of their calculating and unloving acts of betrayal.
–James Hitchcock, History of the Catholic Church
