Murphy described the decision Saturday during a panel discussion at the New Yorker festival.
After gunman in Las Vegas killed 58 people and injured 500 more on Oct. 1, Murphy decided to make the show -- set to air Tuesday -- less graphic.
"I just made the decision that I'm going to have all of that violence be shown for the most part off-camera," Murphy said.
"Should you air it? Should you not air it? How do you be sensitive? My point of view was I believe I have the right to air it, but I also believe in victims' rights, and I believe that now is probably not the week to have something explosive or incendiary in the culture because someone who was affected might watch that and it could trigger something or make them feel upset. So our decision was to re-edit it and I felt that that was the right move," he said.
"Nobody ever talks about victims' rights. That's sort of a weird emotional discussion that's never bridged... But I felt great sympathy for people who were affected, certainly, and family members and loved ones and people who are upset about the way the world is," he said.
Murphy said scene, which was filmed in September, was meant to make "an obvious anti-gun warning about society."
