Would you say that "I won't kill you, but I don't have to save you" is a good adaptation of Bronze Age Batman's specific moral code? And in any case, do you approve of it?
I wouldn’t put it 100% in those terms, but I do read Bronze Age Bruce as being more… forgiving of himself and others for not being able to save villains. Like he wouldn’t breakdown into a deep depression about it, but I do think he would try to save his enemies if possible. It’s a… fine balance.
Honestly I feel like his moral compass lined up pretty well with Oracle Barbara of the Post-Crisis.
