I think he does. For the most part, Thanos would like the universe to be in one piece - only because he lives in it. In the Infinity War and Crusade, Thanos helps the heroes. In Blood and Thunder, he assisted the Watch again. He ain't evil no more but still a badass.
What are the powers of Justice Legion A. I know of Superman 1,000,000 ..who is ridiculously powerful with mental and 5th dimensional imp powers...but what of the others?

Maybe that’s why humans drink the darkness that is coffee.
Theoretically the Gems give the wielder infinite control over each aspect but the only ones who use the gems to their full extent is Warlock and Moondragon. Drax, as powerful as he is, only subconsciously uses the power gem. Pip only uses the space gem to teleport. And Gamora doesn't even know how to use the time gem. The reality gem is (or was) with Thanos but that gem doesn't work on its own, as a ruling from the Living Tribunal.
However, against the Justice League, Warlock and Moondragon using their gems are all you need. Warlock could just steal their souls or trap them all in soul world. Or Moondragon can just mindwipe them all - no telepath can withstand someone expertly using the mind gem.
Now if the Infinity Watch didn't have their gems, the outcome would be the complete opposite.
Gamora knows exactly how to use the time gem. It took her some time, but she eventually learned to control it. She has stopped time, traveled through time, etc.
Pip has done more than just teleport. He has used the gem to defend himself with space distortion, and manipulate gravity. He is an idiot, but he's not useless. No one with an infinity gem is utterly useless.
