Precisely with the situation at Virgin JB can achieve what he desires to do like you mentioned - to burn Qantas and the CEO to ground. With cash injections like this he does not really have to worry about the sustainability of Virgin the way AJ has with Qantas? Not to mention that the fundamental problems are indeed there for Qantas like it or not - Australia not being a world hub like Singapore or Emirates, Qantas has a significantly higher cost base... Etc.
I agree with your point, but I am not convinced that if we swap AJ and JB's shoes with each other AJ would not be able to do what JB has done today.
