Different races have different values, belief systems and empathies also. For example in London when a black boy is stabbed and bleeding on the ground (which happens multiple times daily in London) white members of the public come running to help. This is evidenced by many, many photographs in reports etc. Whereas in South Africa there are youtube videos showing gangs of blacks mugging and attacking whites openly on busy streets and other black people strolling by without a care. Take Japan also. When someone topples off their bicycle on the road it's quite likely that nobody will stop to help. That might seem strange to us, but only because Western values are originally based on Christianity.
