The way I see it is that he announced to the world he was going to do WTF he fancied and "you will not stop me".
We have pretty much allowed him to carry on as he pleases. We have to intervene now and help as much as possible, otherwise he will get the idea that he can do what he likes. He has to be taken down a peg or two.
As for pushing the button, he wouldn't dare. He knows that would be the end of everything and he loves himself too much to do that.
He was a bully as a child and nothing has changed. We need to stand up to him.
