You are conflating the pain of loss with the emotion of anger.
If you have an ounce of humanity, sympathizing with this person should be automatic. They have every right to be furious and there can be no resolution until the underlying material conflict has been resolved. That is the purpose of that emotion, to drive behavior towards affecting change.
The approach/philosophy you are approaching this from is useful for when the brain gets "stuck" after the underlying conflict has been resolved or when someone is hallucinating blame to deal with the pain of loss. There is no possible interpretation where either of those is the case. The situation has been logically analyzed and the emotion has been checked.
If you have an ounce of empathy you should be mad as well. You have been informed of the situation. You are aware of the pain they are experiencing. You understand that without change this can/will happen to you. Why aren't you angry?
