I was stuck by the ‘I am vengeance’ line. I don’ pay much attention to Batman, but I recall one of the 90’s flicks with Robin turning on the difference between revenge and justice.
I might be wrong, but I think this is one of the key threads running through the Batman mythos. Batman has the power to take revenge, and is tempted, but chooses justice instead.
If this is right, I suspect that this will be a self-hating Batman, constructed to pander woke y’alls, whose dominant motive is revenge- not justice.
