“Exceptions to the rule do not invalidate the general principle that restraint by capital punishment and warfare is grossly ineffective and highly perilous.”

"A Letter to the Friars Minor" (1334) as translated in A Letter to the Friars Minor and other Writings (1995) edited by A. S. McGrade and John Kilcullen, p. 204.
Context: The head of Christians does not, as a rule, have power to punish secular wrongs with a capital penalty and other bodily penalties and it is for thus punishing such wrongs that temporal power and riches are chiefly necessary; such punishment is granted chiefly to the secular power. The pope therefore, can, as a rule, correct wrongdoers only with a spiritual penalty. It is not, therefore, necessary that he should excel in temporal power or abound in temporal riches, but it is enough that Christians should willingly obey him.

Context: Capital punishment is the most premeditated of murders, to which no criminal’s deed, however calculated, can be compared. For there to be an equivalency, the death penalty would have to punish a criminal who had warned his victim of the date on which he would inflict a horrible death on him and who, from that moment onward, had confined him at his mercy for months. Such a monster is not to be encountered in private life.
