For people who are doing horrible things in the society, destroying themselves, we usually get angry at them. When you are angry, your mind suffers a huge loss. You lose so much energy, you lose your mood, and your enthusiasm. When energy and enthusiasm goes away from you, you become angry and are no better than the other person. You do not know what you are doing. So, what should you do in such a situation? Have a sort of indifference in your mind.
For example, there are thieves in the world, they are there, what can you do about them? First accept, be indifferent. However, this does not mean you do not take any action. Your mind is indifferent (unaffected), but you act on it.
