If a man lied, cheated, and insulted me in real life, my response would be similar to what I wrote.
I don't really even know how the UIF guys are supposed to have tricked you, so I won't comment on that. However, I do seem to remember you guys stringing them along for ages with claims that you didn't really have any ties to the Templars anymore (the same line they used on Kapikulu, HRE, Fallen etc, hilariously enough). Of course they, your closest allies, have shown themselves to be traitors and liars of the highest order, but you didn't mind then because it was to your benefit. You all seemed to think it was a perfectly natural way to play the game.
That was also yet another case (on top of the more recent Green one) where UIF ganking saved your hides, but now you've somehow managed to get all the people they beat for you in the past to work for you, the only possible protector by virtue of being the last ones standing. The way you've hoodwinked them is kind of impressive, but the double standards you're employing don't really stand up to much scrutiny.
