Children are the epitome of innocence in the meaning of the word for: moral discernment between good and bad. In moral philosophy the reason why someone is culpable is because they understood the negative consequences of their actions but decided to do it nevertheless. This is, for example, in the law, there is a difference between murder and manslaughter. Children must be taught morals. Another example is in Christian morality. The original sin is the ability to discern between good and evil. Thus the loss of innocence of humankind.
