Khmer Rouge

I did alot of reading up on this particular group, and i was appalled to know that the group had NO REACTION to what they were doing! personally, killing ONE person would really mess me up, but these men killed millions in cold blood, and not only that, but they killed men women AND children! so i did a little bit of thinking, and i find it sad that man can act so irrationally; when the veitnamese soldiers were allowed to enter Cambodia to retrieve supplies during the war, they took advantage of the weaker Cambodia, and almost brainwash them with their communiat ways, which in turn caused the Cambodians to turn against themself and literally kill off most of their own people. absolutely appalling. thats all
