Perhaps we should consider that there are some countries where it is not proper for us to be offering such education? I can name very few countries deserving of nothing more than basic food and medical and North Korea is one of them.

Don't throw the guilt on him or others,their fate is already abysmal because of their government and sending them a few teachers is not going to benefit their society and if its for feels, well they are misdirected and other countries are far more deserving of our time
