The most insidious form of education is teaching people to be kind but never revealing the true nature of society. Those who often teach you kindness are actually very evil, equivalent to sending sheep into a wolf pack and then telling you that the world is full of love. Schools won't teach you how to defend yourself, and parents and teachers may not understand the rules of social survival. Some people's children understand the laws of human nature by the age of 10, while others' children will spend their entire lives enduring hardship. Constantly enduring hardship is a form of cruelty to oneself. If you don't understand these things, you will always end up fueling others.
