Who killed Ra's Al Ghul (Head to the demon)? BATMAN OR ARROW
I see. Did this event have any significant impacts on Batman's character or the other characters in the Batman universe?
Yes, Batman killing Ra's Al Ghul had an immense impact on his character, as it went against his no-killing rule. It also affected his relationships with other characters in the Batman universe, including his sidekick Robin and his ally the Joker.
