Unfortunately people who abuse others will be remorseful, show hope in getting help but then fall back to abusing again. There's typically a honeymoon phase, where they admit full fault, then are super nice. Often they might be sincere but just can't control themselves. The victim believes every word and falls deeper in love. They have endless hope, that eventually will dwindle while the self esteem crumbles. Hitting full force 6 times on the head could seriously cause brain damage or worse.
