Traitor.
Dont get me wrong, im relatively patriotic. But i dont want to get shot by men with big, angry, high powered rifles at close range.
I would hand over all information i had available, at the time, and promise them more if they let me live, and give me a 1-way ticket out of the country.
Sorry guys. But my role is that of "he who joins the side he hopes will win". And if wars broken out, and were caught off guard, its most likely going to be the enemy side.
On the off chance that our side does start to win, i steal all information i can find and turn it over to the "good guys", and say i was playing the double agent all along.
Its part of being Lawfully Evil. Siding with whomever sets the laws and benefits me most!
