“his religion permits him to rape her.” .......................... Odin says that he should have his little brain smashed by the hammer of Thor or removed by the axe of Höðr. Forget this turn of the cheek and forgiveness stuff.
If you can’t lay hands on Mjolnir the Hammer, then a .38 wadcutter to the rapist’s head would interrupt his wicked act without too much noise or fuss.
Or, a captive-bolt gun such as used in slaughterhouses would provide an even quieter response to a rape in progress, also with zero recidivism.
