Annie killing the Deep would be very satisfying sure
I also think it would be satisfying for Annie to essentially decide he's not worth the little bit of effort it takes to kill him. But Homelander sees that she spared him and thinks he's a secret turncoat (the deep is of course too much of a coward to be one) and kills him instead.
I just think the idea of Homelander killing or driving away all of the Seven out of paranoia makes sense for him. Cannibalizing the only people he thinks he has left.
The exception to this is Sister Sage, I really can't figure out her deal. She either has a secret plan or is being used to show even the smartest people fall to power (an absolute power corrupts absolutely situation) Fingers crossed for the first option but "smartest person in the world" powers are the most difficult to do since they're usually being thought of by a writer untangling 50 different plot threads.
