I pretend to like people sometimes, that is not manipulation. Sometimes you do it to keep the peace or to avoid conflict.
There are many reasons people pretend to like others that are a world away from manipulation,manipulating someone you don't like to give you something or do something for you is manipulation in part.
In the BB house though, I cannot see any other personal gain whatsoever that Aaron would want or need.

He knows he has topped the votes in every eviction battle he has had, that is the only key to success on a BB series, he is in the final, what on earth could he need to gain by manipulating people.
The viewers will decide the winner, the housemates largely irrelevant now. Most of them have done their utmost to bring Aaron down with the public,they have failed every time as he's topped every eviction votes.

I'm sorry but I really cannot see your point as to what more he could gain by manipulating other housemates at all, there would be no point when you are already top of the votes with the public anyway.
