People do not care for impious life. That is misfortune. No knowledge. Impious or vicious activities are done out of ignorance. Just like a person commits some criminality without knowing the laws, government laws. Ordinarily, just like in your country, "Keep to the right." If you drive your car on the left side, immediately you become a criminal. So in our country the car is driven on the left side. In this country the car is driven on the right side. So if some Indian gentleman says that "I am accustomed to drive on the left side. So what is wrong there?" "No, this country's law is 'right side.' You know or do not know, whatever may be in your country, because you have driven your car on the left side, you are criminal."
So ignorance is no excuse. In the law court if you say, "Sir, it was not known to me," so that does not mean that you will be excused. Similarly, knowingly or unknowingly, if you do something sinful act, then you are immediately criminal. You'll be punishable. It doesn't matter whether you know or not know. Just like fire. This child, if he touches the fire, the fire will not excuse. There is no consideration, "Sir, here is a little child. He does not know this fire is burning." But as soon as he touches, it will burn. This is nature's law. You infect some disease knowingly or unknowingly, it doesn't matter, but the disease will be manifest. Suppose you have infected smallpox infection, contamination. Then it will be manifest.
