That said, sometimes severing ties with an elderly parental abuser is necessary partially so that siblings or extended family don't perpetuate the cycle by expecting the scapegoat to continue to do the work of providing care while also taking the blame from both the abuser and other family members. Sometimes the scapegoat needs to take themselves out of that situation and let other everyone else figure out what to do instead of just heaping it all back on them. Remove that option and other people might step up and find better, more viable solutions.
