Chapter 8 opens with the story of Erkenwald and the righteous pagan judge, inviting the reader to consider not only the complexities of defendants’ mental state, but also the mental state of persons engaged in the act of judging; this, too, would be subject to scrutiny at the Last Judgment. The chapter argues that medieval English felony law was based upon the equitable balancing of harsh justice and mercy; for a justice or jurors to stray too far in either direction could be condemnable. Drawing upon cautionary tales about judging, the chapter highlights themes that appear in medieval English literary and religious sources, including the notion that justices should not waver too greatly in decision-making, being swayed by money or ill advice; that justices should also not be too inflexible, but should rather reconsider a judgment that in hindsight appeared to be mistaken; and that justices and jurors should beware lest their decisions be informed by anger rather than measured consideration of the facts. The chapter illuminates the ways in which mind mattered not just for determining the culpability of criminal defendants, but also for assessing the culpability of individuals tasked with sending felons to the gallows.
