Batman V Superman's Writer Explains How Batman's Ending Could Have Been Way Darker

This was just one of many aspects that Chris Terrio changed about Batman v Superman: Dawn of Justice when he rewrote the script, but it certainly did the trick of making it abundantly clear that Bruce Wayne was clearer-headed following Superman’s death. Besides, in the Ultimate Edition of the movie, the Dark Knight still got to exact a fitting punishment on Lex Luthor, as he made arrangements for the supervillain to be moved to Arkham, which is not one of the DC Universe’s better mental institutions, to put it mildly. Once that business was taken care of, Bruce was ready to start looking for other heroes to help him protect Earth, paving the way for the events of Justice League/Zack Snyder’s Justice League.
