Validation is a tool for assisting in healing. The more hurt and dysfunctional a person is, the more that person is in need of the tools of healing.

In my view, all hurting people, by the fact of their being human, deserve the opportunity to heal. I myself might not choose to be the one to provide that opportunity, and they might choose not to accept it, but all deserve to have the opportunity available to them, in my view.

One would not validate their treating people like crap. One would listen and observe until one found something that is valid in what they are doing or feeling. One would then acknowledge and validate that.
