Same thing happens all the time in big cities. An elderly in Stockholm got mugged and beaten by a gang and people were just walking by.
It's a part of big city mentality, people care less for each other and objectify each other because of how many people live there. China is one of the countries with the largest population so I would think they cared even less for human lives. This is probably why some countries with small populations (Iceland, Sweden, Norway, Denmark, etc.) care so much more, have strict gun laws, etc. care more for each other in general (as I said, this occurs everywhere tho).
Yes, yes I'm back.
Somewhat.
