I've heard many times that science fiction is social commentary. "Death Wish" (Season 2, Episode 18) of Stark Trek: Voyager is a very obvious example.
The story centers around a physically healthy and immortal person who wishes to die. To prevent his suicide, other immortal people have imprisoned him. Through some circumstances, he is freed and given the chance to debate why his suicide should be allowed.
One of his speeches (sorry for the text):
The story stays somewhat neutral on the suicide debate, until perhaps the ending. You may recognize some of the simplistic arguments used. Maybe you have even made some of the arguments yourself. The writers did their homework.
In one instance, the person argues that not being able to die cheapens his and everyone else's existence. Outside of the story, opponents of suicide can claim an opposite argument. They can claim that one person's death
cheapens everyone else's existence. I have no idea how to reconcile these arguments.
I find this story interesting because the person wanting suicide is not dealing with physical pain or a deadly disease. The writers could have written a safe story about either of those justifications. Instead, the writers picked justifications that were harder to defend, such as boredom. And boredom seems like a rather taboo justification for suicide.
Overall, I think "Death Wish" is a decent presentation of a debate on suicide for a casual audience.
