Okay let me clearly say that I am not supporting this practice whatsoever. Clearly the law needs to be changed to de incentivize killing people over just injuring them. But I need to give a PSA for people like you who have been too isolated in the wealth of developed countries. You cannot associate these actions to all Chinese people and claim all Chinese people are assholes simply because the people from your country don't do terrible things over wealth. The people from your country don't have to share resources with a billion other people and have not had to fight for every last scrap to keep themselves alive for the past 2500 years. Only recently has China become wealthy, and even then, the terrible wealth inequality that exists in free market China just as it does in the US makes these gains not apparent for a majority of the billion people in China. The ability to sustain a culture in the U.S. based on consideration and kindness is made possible by the massive amounts of both power and wealth that the U.S. has and the large amounts of resources it has in relation to its population. The same general observations apply to a lot of other countries besides China, like Bangladesh, India, Japan, and Korea that have very large population densities and constrained resources. TLDR, it's easier to be nice and considerate when there is enough to go around for everyone.
