i dont see that... tony is the one who is suggesting to start the attack instead of waiting... I think the only reason he didnt kill JAck is he assumed he is going to be seizuring out and dead soon and is not a threat to him, in addition at that time no one else suspected Tony, and if he had killed Jack it would have given him away sooner, so by not killing jack it gave him more time to escape
tony has turned into one Bad A55 dude....
