budd' theory has contradiction itself

Budd pursue "universal love" but isolate man an woman completely, so after old people died, no young people live in the world. "CI BEI" is inherently "Cruelty" and remove people completely from the planet.
Budd tells about life circle and your conduction determine the position in the circle, but who determine my first position before I do anything?
Budd change China from promising Tang Dynasty to a very weak country and holified the govern and encourage people to tolerate even flaying skin like Tibet buddism. Horrible religion!
