The biggest betrayal is a point of view. I wouldn't have said this is the biggest betrayal at all, although there have been numerous betrayals in world 2. I don't think there is a tribe or family tribe that was no betrayed at some point. From my point of view, this point in time was justice, from yours it is betrayal. Reality is, it made the world more interesting for a time.The biggest betrayal ever was when HOT joined ATEN fighting against TW. It was fun though because the centre of W2 had been a sea of blue for so long.
