Fan Casting Clark Kent in Batman: Dark Knight's Pain

In this universe, the events of me and @riddleymoscu's Batman V Superman trilogy remain the same (with a few differences, of course). But unlike in the original ending of Batman V Superman: Unchained, where Batman spared the life of Superman after defeating him through the use of his Kryptonite-powered suit, Thomas Wayne took the physical beatings way too far and ended up killing Clark Kent, which is why many people hate the Batman in this universe. And unlike Bruce, Thomas doesn't care whether or not his enemies live or die (except for the Joker), even carrying firearms into battle with himself.
