Michael Dorn questioned Lt. Worf’s decision in an episode of Star Trek: The Next Generation, as Dorn was worried that fans would think the Klingon was a murderer. As the only Klingon in Starfleet at the time, Worf was often torn between his desire to embrace Klingon culture and his duties as a Starfleet officer. After the death of his biological parents at the Khitomer Massacre, Worf was raised by humans on Earth. Because of this, he already felt somewhat disconnected from Klingon culture, but this TNG episode emphasized that Worf was not human.
