I get so infuriated when people reduce Jason's ultimatum to "trying to force Bruce to kill someone to prove his love". The dishonesty of it. Remove all context from the situation and make it sound like an insane inhumane choice. I can do that too actually. Batman is a rich kid who whales on poor and mentally ill people instead of going to therapy. He colludes with cops to bypass due process and collect evidence illegally. He creates child soldiers and makes them into canon fodder for his obsession. It sounds pretty indefensible when you remove every single context and convention that makes a story work doesn't it? Almost like you're only willing to extend the in-universe rules to the rich white manbaby and not the child whose death he was responsible for, huh?

Also? Moral absolutism is harmful and egoistic. You shouldn't kill people, not even criminals, of course not. But that doesn't mean refusing to kill in any situation whatsoever is the moral choice. There's a difference between killing to protect and killing to avenge. Between killing an active threat who will definitely escape and slaughter a family and killing one who is safely contained. Any rule that's taken purely prescriptively and without regard to the individual context of the choice is simply dogma. Especially if the role you have voluntarily taken on requires the willingness to do whatever it takes to do your fucking job. That's why morality isn't fucking black and white.

That's the crux of it for me; why I take this defense of Batman's choices so personally. I don't trust people who see the world in such a black and white way (this includes Jason, who is exactly as myopic as Bruce, but happens to be right about the Joker imo. Fortunately he's a fictional character and also a kid who has not yet had the opportunity to grow, unlike Bruce). I don't trust people who think morality is about a set of correct judgements rather than the process by which you arrive at said judgements. I don't trust people who won't fucking choose. Inaction is complicity, bitch. The consequences of your choices exist and fall on other people regardless of your refusal to take responsibility for them. Bottomline – if your version of "mercy" results in the death and suffering of other people, maybe consider that you're the villain of the story.
