Jason needs to go back to dating Artemis and just switch from being a bat family faggot to one of Wonder Woman's sidekicks and extended cast, since she's also in the "I will not feel guilty for beheading unrepentant monsters and mass murderers" camp and Jason won't constantly have to defend himself from behaving like a completely reasonable and rational individual after his psycho daddy knocks his teeth out for daring to shoot live ammunition at the Joker and Scarecrow after they escape Arkham for the 100th time.

Dark Trinity with Bizarro and Artemis was the best situation Red Hood was ever in because he was allowed to actually do shit on his own terms without constantly dealing with the same tired retread of whether it's okay to shoot people or not that nobody else in the setting deals with.

Just have bats lose the custody battle and Jason ends up staying with aunty Diana, and then have the lessons he about learning compassion and ensuring the side effects of the Lazarus pits don't control his personality (and since she's explicitly magical and divine in nature she can actually acknowledge the Lazarus out shit instead of pretending it doesn't exist like Batman or that even if there are side effects it's still his fault for being murdered lol), and have the conflict be when you change from an offered hand to a closed fist or drawn sword, with killing being a last resort rather than completely verboten for retarded editorial mandate reasons rather than any in-universe justification.
