These abusers need to be tied to a house post, handcuffed and be allowed to run around the post. Let the woman and her family do the beating and let's see how he feels. I saw this happening in one African country to a bunch of teenagers who raped a woman. There were about 4-5 naked teenagers tied around the post and a bunch of women doing the beating.
Did the beating significantly reduce rape in that country? If not, then something else is needed - like mental rewiring.
