it is a very tough。

job to teach a child as parents. For example, we all want our children to be a decent person. At the same time, we will also need to teach them to how to play tricks, sometimes those tricks are in grey areas. 人之初，性本善?? do not think so. Without teaching/training, it is difficult to imagine a child will be a 善 person. Being selfish is the evolutionary pressure for selection. Of course w/0 善, the whole group may suffer and being selected against.
