Batman still won, even with a broken back. If you want a Batman-Wentz broken back parallel, he’s doing pushups in a cave right now, getting ready to illogically defeat a nuclear bomb.
You are right. Batman beat Bane when Bane broke his back. It is the exact same thing as when Wentz torn his ACL and helped win Super Bowl LII. It was a sight to see, watching Wentz run all over the U.S. Bank field that fateful day.
Wait. Wut?
Seriously though. Comic book heroes usually (but not always) triumph at the end of a story arc but they do not win every fight. Anyone can say Batman wins
every time but they are either only lying to themselves or do not have a clue. I wish Jason Todd could do a Q & A about whether Batman wins 'every' time, lol.
