As much as they are flushing Black Adam down the toilet right now in JSA, they are fleshing out Sinestro... balancing the scales.
Sinestro has been playing the "long game" for a while now, moving his daughter into a position of prominence on his homeworld. He knows his people and their needs, and for all the evil he has done, he does make very solid and valid points as to why he does what he does.
This, of course, makes him the most dangerous kind of villain... the kind who truly believes he is doing the right thing for the greater good.
A couple of things...
Oh, and the image of Green Lantern Sinestro flying with his daughter... the wonder and awe and pure joy of a child in her eyes... awesome and heartbreaking.
And the need of a father to go out and tame the world and universe from doing any harm to his family and child, by any means necessary.. I can understand and appreciate it. Especially if Sinestro knew about the prophecy of Blackest Night and what was coming.
And yes, this feels a lot like the Skywalker / Vader talk at the Cloud City.
