Through a series of events of which the details don't really matter that much you have found yourself in a foreign country you've never been to before. Why you're there doesn't really matter, all that does matter is that this country is only moderately stable and the majority of the population do not practice your religion. What religion they do practice isn't really relevant; all that matters is that it is entirely dissimilar from your own, looking almost alien by comparison. Through a series of controversies and scandals the stability of this country becomes increasingly threatened as time goes by and despite your best efforts to get out before things get too bad, your efforts bear little fruit. Before you know it you're trapped in the country with no way out. As bad goes to worse the tolerant, secular, democratic is overthrown by a group of fundamentalist organizations who establish a radical theocracy and impose their religious laws on the rest of the country. As most of the country is fairly devout and already willingly follows these laws there is little opposition to them or the new theocratic government. However, the government has made it a point to persecute unbelievers - be they heathens, heretics, apostates, or atheists - to an extreme degree by having them arrested and forced to convert to their religion or be executed.
You are able to locate the nearest embassy/consulate of your home country, however despite taking refuge within their walls the new government has shown it will pay no respect for diplomatic immunity and has violated several embassies/consulates already. International condemnation, embargoes, sanctions, and even threats of war quickly follow but these are the least of your concern right now. Unable to escape you've been arrested and through the testimony of several witnesses, your true religion has been discovered by the zealous leadership and you've been locked in solitary confinement. An interrogator soon enters your cell and demands you renounce your religion and embrace his own, or else you will be executed. He informs you that once you convert you will not be permitted to leave the country ever again and will be under constant, armed surveillance and guard for the rest of your life to ensure you practice this new religion properly and do not embrace the practices of your old one. You will essentially be a hostage for the rest of your life. Chance of escaping or rescue seem slim. You have not been told nor have you of how you will be executed if you refuse to convert. There is an even chance it could be a long and painful method or a quick and painless method. Attempting to ask the interrogator which it will be yields no answer nor response from him. He demands once again you convert or die.
You have a choice:
1. Convert and embrace a religion you don't believe in just to survive. Maybe one day you will be able to escape and be free to practice your true religion again. You hope your god/gods will understand.
2. Refuse to convert and go to your death. You have nothing to fear, for you've proven your piety and are confident that you'll be rewarded in the afterlife for your unshakeable faith.
What do you choose?
