Personally, I think the vendetta would be against Splinter. Shredder mentioned in "New Girl In Town", about what Splinter had "taken from them". (Most likely he was referring to Karai's mother.)

This storyplot is kinda like in the film Zorro. You know, with the villain and the hero both in love with the same woman, she marries the hero, has a daughter with him, and during a fight between the 2 men she accidentally gets killed, and the villain ends up taking her daughter to raise as his own. I think the same happened with Splinter's daughter, Miwa, and Karai is her.

In a way, it's the perfect revenge. Horrible, but ideal in hurting your enemy the worst. After all, what's worse to a dad than to know your own child was raised by your worst enemy, and that she's been raised to hate and want to kill you?
