就和法律是一样的，没有惩罚，就没有畏惧。不触犯法律是他们做人的底线，但犯罪成本又很低，导致法律反向鼓励他们犯罪的话，人们应该主动惩罚这些人。法无为，人有力。只有惩罚才可以制止他们。温和的说教无用。
Just as the law is the same, there is no fear if there is no punishment. Not breaking the law is the bottom line for them to be human, but the cost of the crime is very low, leading the law to encourage them to commit crimes, people should punish them on their own initiative. There is nothing to be done, people are strong. Only punishment can stop them. Moderate sermons are useless.
