this is very interesting thread. also I do think she could kill the force due to Malachor 5 unique status within the galaxy. By killing a wound within a wound in the force might have an interesting effect.
Also non force senstives probaly not be effect by the loss of the force if it was going to happen. Mainly due to their low connection to the force. conversly the stronger connection to the force, more painful to have the force to be stripped from you.
