Dependence on intimidation
Any excuse will serve a tyrant (Aesop, The Wolf and the Lamb).
A threat can be just or unjust, good or bad, depending upon whether the threatened retaliatory measure is morally justifiable. The sanction normally attached to positive law is, in effect, a threat of punishment to be inflicted upon its transgressors. To threaten punishment may therefore be reasonable and virtuous, and a parent, teacher, or a custodian of the law, would fail in his duty if he neglected in some circumstances to threaten punishment. Prudence and care for the society and the individual to be threatened must dictate the norms to be observed in making justifiable threats.
