How many North Koreans does it take to change a lightbulb? Two. One guy to screw it in, the other to shoot him for not doing it right.
Why would you say something like that about people from North Korea?
I'm sure they all have military training and shooting defectives sounds like a fun thing to do to me.
North koreans are people just like us and I'd even go so far as to say they are forced to sometimes kill their countrymen. Blame their government for the violence in their country, not their people.
