This view seems predicated on the idea that people who estrange their parents do so because of past actions. I'd argue that in my personal experience and my experience with other such adult children the reasoning is more often about the current behavior of the parent or parents than past behaviors. People who abuse or neglect their children are often doing so because of their own mental illness or emotional instability and those issues are unlikely to resolve without outside help.
