Something though that always made me wonder about Earth-3--this whole "moral cosmology" thing of DC's. I'll just use one example: Power Ring, whose ring works "against justice." I don't want to get into a huge philosophical thing here, but seems to me that begs the question of how "justice" is defined on Earth-3. I realize it's not like Bizarro World where everything is absurdly opposite, but if the country and the world are the way they're described, the concept of "law" and "justice" would be vastly different just on the normal-person level, and perhaps what they do might not be considered crimes. I mean, it makes you start to wonder just how any society would be able to run. (which might be an argument for their being gotten rid of in the Crisis--they represent a very simplistic good-vs-evil view left over from the Silver Age JLA)
I'm thinking of something like DEADWOOD, which despite its sheriff is pretty much a place outside of usual ideas of law, but just the same, these people have to live with each other, and like most would rather be comfortable and make money than kill people, so a different type of order arises anyway.
Also: "Justice" is in the eye of the beholder to a large degree, as are "good" and "evil." So that begs other questions too. Power Ring might consider it very just that he steals Fort Knox with his ring or something(oh wait, though, gold is yellow).
