Can you clarify your logic? From what I read:<p>1. It is basic human instinct to not hurt people. 
2. Training can overcome this instinct. 
3. Therefore these murderers must have trained themselves. 
4. Therefore there are a lot of people in China who must have trained themselves to kill. 
5. This all reflects badly on all of China when citizens visit other countries.<p>Can someone explain why it is reasonable to assume that mental training (2), as opposed to perverse incentives and corruption as the article mentions, is the only way to overcome (1), and why, even assuming (4) to be true, (5) is also true?
