I think option B is the more reasonable one (although it could be the wrong one). Why ?
First , the god doesn´t say what "remove suffering" means. It could mean:
- The god destroys the earth, so there´s nobody to suffer.
- The god let men live forever without feelings and reason. All the people know is, that I chose option A.
- The god does nothing for humanity because he sees no suffering and let me experience my worst nightmare.
If I shall experience my nightmare, he´ll probably choose the interpretation which is the worst for humanity.
Furthermore, do I not know, what the sense of life is and who or what I really am. So is removing the suffering really good ? Is it probable, that the sadistic god will try to help me with option A ?
BUT, option B could be the better one, e.g. if humanity would soon experience the worst nightmare anyway (or sth even worse).
If I found out, that a person chose option B, I would gratulate him to a reasonable choice. The world is no lab.
