Weapon of mass destruction
Here's the situation:
You're the best scientist your country has. Your country is involved in a war. The government asks you to create a weapon of mass destruction. You are the best person to do the job in your country. The enemies have already begun to create similar weapons. Would you create the weapon and defend your country, knowing that if you refused your country would be unable to beat the other in making the weapon, and quite possibly killing most of your fellow countrymen? Remember, you're the best person for the job. If you refuse, the others who would work on the project would be unable to beat the enemy in the creation. You're the only one that stands a chance in doing so. Refusing to do so will not end the war. Agreeing to do so won't necessarily end it either.
What would you do?
