The Council does have the power to kill warlocks but they do NOT use magic to do so. There is a reason that the Wardens carry swords. Similarly Harry can kill warlocks as long as he doesn't use magic. Hence why he carries a gun. In regards to the sixth law the council has an even better reason than usual to outlaw time magic...Paradox. When a mistake could concievably destroy the universe its better to be excessively cautious.
