Considering that James Gunn also admitted that he has been inundated with messages from individuals that have been adopted and have step-fathers thanking him for his work on Guardians Of The Galaxy Vol. 2, it appears as though his decision to kill off Yondu was the right one, too.
However, the fact that Yondu’s death in Guardians Of The Galaxy Vol. 2 symbolized what the entire film was about meant that he had no choice but to go through with it.
In order to do this story justice Yondu needed to die, otherwise James Gunn admitted that he would have been “backing out” of this thematic exploration.
During the online discussion, James Gunn admitted that the film is about a father’s true love for their son, and how our real fathers and brothers transcend beyond blood.
