The thing is, if Teach really does want revenge, he has a S + level pokerface about it. Like I don't think he's ever shown a true grudge to anyone, he's that utterly amoral. Like even if he knew Ochoko betrayed his dad, I bet he wanted Fullalead more then just revenge.
But that said, if I am indeed right and he is merely waiting for Luffy to soften up Imu so he can stab him in the back, yeah, he probably will enact some level of revenge on the Celestial Dragons. It's not Oda's way to have them utterly exterminated, but enslavement should be some level of sufficient karma.
