The will is referred to as the appetitive power of the soul or the rational appetite. Like the intellect, the will is a spiritual faculty. It is that power through which an individual seeks to execute an act or attain to an object proposed to it by the intellect. The object of the will is always the good, and even in the election of evil, it must be proposed to the will under the appearance of good. Anything chosen as a means is therefore viewed under some aspect of goodness.
Therefore because in all voluntary acts choice is subsequent to a judgment upon the truth of the good presented, declaring to which good preference should be given, it is an immutably true principle that human liberty depends entirely on intellectual judgments that conform to reason and the natural law. If a judgment which does not conform to the natural law or to reason, and which is, therefore, objectively false and immoral, is acted upon by the will, then it is a source of grave disorder in society.
Exponentially multiply the number of individual immoral acts, and you have a Republic that collapses from moral decay in a short period of time.
