This is mostly the story of Mark Anteus. He's a metahuman who saves people, a lot. That eventually, after some upgrades, gets the attention of the JLA and he becomes a reserve member. Unfortunately, because he's so over passionate about saving the 'innocent' and punishing the 'guilty', he can't seem to see the greys in life and so his stint in the JLA goes all to hell.

The story basically asks the question, should the super powered take out governments, dictators, if they are of the opinion that that organization/government is causing harm? The story mostly answers that question, but not totally. It's an interesting facet of the philosophical part of super powers. ( )
