People on earth are good at living. The same nature varies from upbringing to upbringing. Without education, there will be deviations. What do you mean?

"At the beginning of life, human nature is good."

People are naturally kind.

"Sex is similar, learning is far away."

Good natures are very close to each other, but because the environment and learning environment are different in the process of growing up, there are differences in temperament.

"Don't teach, be sexually active."

If we have not received a good education since childhood, the nature of kindness will change with the influence of the environment.
