Re: It's not just them..
Obsidian has the excuse of being insane. As for Alan Scott, I don't see who his ex-wife reflects on his character.
Atom Smasher was a hero who killed for no tactical reason. He overthrew a freakin' country and helped set Black Adam up as dictator. Yes, he got a pardon from the Suicide Squad, but he got that because he was part of an underhanded smear campaign against Black Adam. Rather than speak out and reveal what happened, he blackmailed Waller for his freedom.
So Al's a killer, traitor but still belongs on the JSA? Fuck that.
