Someone should make a heatmap of the Superman D&D moral alignment chart and see how frequently each of the nine squares are told. I've seen a version of that chart where Action Comics #1 Superman is chaotic good, and I'd probably guess that Chaotic Good is one of the bluest squares, somewhat ironically. But specific to Injustice, I think chaotic good would be the natural evolution for the character, not the mustache-twirler the game version of the character becomes. The game's story can't seem to decide if Superman means well and that's why he assumes power, or if he's just turned into a bad guy.
