Lots of panels in Injustice are popular. That one in context is Hal following Supes into authoritarianism and forcing them to do what the Regime wants. It’s his first slip down the slippery slope that ends with him as a Sinestro.
Nobody in the story is in character, it’s just hand waved away with “Elseworld” because none of the JL is going to follow Supes once it’s clear he’s lost it. WW is the worst case though.
