If you were in solitary confinement for the rest of your life, and you discovered a cockroach in your room, would you kill it or make it your friend?
I'd name it (him? her?) Gregor and maybe it would do whatever cockroaches do that is similar. I doubt that my captors could have a great deal of concern for my comfort or safety, so what possible additional harm would a cockroach be? If solitary is really solitary, the opportunities for fresh perceptions of reality would be almost endless. Perhaps i would go mad, but what is madness but the failure of self-defined sane people to comprehend somebody. Since other humans would be irrelevant (if solitary were truly solitary) the possibilities of a human/ cockroach relationship might be interesting. This is assuming that no other cockroaches entered the cell which is unlikely since they can go almost anywhere. To be the single "alien" in a community of roaches might cause a rethink; but one cockroach and me would not seem to be much of a problem. Would i make it my friend? I would try, but i don't make friends easily. Now i am thinking of the movie "enemy mine" which poses a similar issue though the "non-human" character does not much resemble a cockroach. The "human" ends up defending the "alien's" child against other humans.
