" The Border reivers were aggressive, ruthless, violent people, notoriously quick on the draw, ready and occasionally eager to kill in action, when life or property or honour were at stake. They were a brave people, and risked their lives readily enough; when they had to die, they appear to have done so without undue dramatics or bogus defiance which would have been wasted anyway. They lived in a society where deadly family feud was common, and when they were engaged in feud they killed frequently and brutally, as we shall see. When they were not engaged in feud, they certainly killed less readily. Their ordinary reiving did not, perhaps, entail quite as much bloodshed as one might expect in the violent circumstances. Bishop Leslie and Scott explain this by pointing out that the Borderers regarded reiving as legitimate (which is true), but that they held murder to be a crime, and consequently were reluctant to commit it—except in the heat of action or when covered by the virtual absolution of deadly feud. It is rather like saying that a heavy drinker, in his sober moments, is an abstemious man. "
