Of course I am going to support Guy A because HE IS MY FRIEND or FAMILY.

But the fact remains your strategy will only lead to your death and your family’s. Which it would be good for your family to know.

Of course you are free to support abusive behavior but especially with friends and family it would probably be useful for your own sake not to do so, and it is factually correct to view (and treat) you as enabler if you continue to do so despite knowing about the abuse.
