Here’s a recipe for promoting spousal abuse and other violent personal crimes: Recruit people for sports like football and boxing or induct them into the military. Then spend the entire time you have them training them to fight, attack, do physical harm, and perform other acts of extreme violence. Focus on harming their opponent, who is an enemy to be defeated at all cost. Mold them into fighting machines whose objective is to win.
When you’re successful, don’t be shocked when the violence they’re trained for and live with daily spills into their private lives. If you don’t want that to happen, maybe you should modify the training.
