ngl i reesent how easily she let off the hook in injusticee
she was complicit in the joker's evil
it was bullshit
nah fuck that , she was rolling with jokeer when he tricked superman into deestoring his city and killing his wife
she knew he was a fucking nut and rode with him, actions have consequences
and it drove me craxy how gl, bats and some other leeaguers were terrible friends to supes in his time of neeed
It's a bit more nuanced that that.
On one hand, yeah, Superman didn't get the comfort and support he needed from his friends, but there was a variety of reasons for that. For starters, Bruce TRIED to reach out and be there, but given the events that happened, Clark put much of the blame for the deaths on Bruce for not killing the Joker himself years ago.
Plenty of other heroes were also shaken by the deaths and it made many of them fearful of a similar incident (very much reflective of post-9/11 where otherwise good people began trading freedom for security). You had heroes like Flash realizing his family was just as much at risk and trying to talk Clark into a more "middle" solution, but piece by piece Clark became slowly more authoritarian as the grief lingered. Wonder Woman is, yeah, one of the weaker "falls", but even that is explained by her literally trying to heal his sorrow by telling him she'll literally be anything he needs her to be because she's always viewed him as the greatest, most noble man she knew... which only enables his actions instead.
This was compounded by heroes like Green Arrow "backstabbing him" by hiding Harley from his wrath, and the other heroes that supported Oliver's decision. And ultimately, that's the thing. Everyone remembers "evil Superman", but this division of trust and split within the hero community - plagued by fears and insecurities - just broke EVERYONE, not just Supes. Hal, Barry, Bruce, Arthur, Diana... everyone was a mess.
Which is why Harley's situation is not so black-and-white. For starters, she wasn't really let off the hook. If Superman wasn't openly admitting he would murder her if he could find her, she'd be in criminal rehabilitation and serve her time, but the situation made that impossible. Her arrest would just be a death sentence when the courts would no doubt rule as not-guilty for reasons of valid insanity and then Superman would find and kill her. For the entire Injustice comic, she's never given a pardon; she's an outlaw to the Regime and a fugitive from the law. The majority of the superhero community did not forgive her and almost all of them on Superman's side want her dead for her role.
But the comic does explain why she deserves a second chance. She was legitimately delusional, and saw the events of the death and bombings from a sense of detached reality. She literally wasn't grasping the consequences of her actions and as she recovers - and starts taking her medications again - she becomes horrified of the truth.
Reality took the place of her mental fantasy. Under the care of heroes who kept her safe, without the Joker's influence, back on her medication, she became SANE again. And with that sanity she bonded with the heroes she once gleefully fought against and felt the responsibility to atone. One of the scenes I really liked was one of the villains saying the safe thing would be to do fall back in line with them, know that she'll never be forgiven. They even put a bomb in her head to blackmail her into helping commit another terrorist act against the Regime that will hurt a lot of civilians. "You don't really have a choice."
She refuses. "I have a choice."
She's not universally accepted, but she's actively working towards recovery. She backslides, has setbacks, but she's moving forward. That's what I like about her journey in the Injustice comic.
