Prabhupāda: Our real business is how to become Kṛṣṇa conscious. So simply for improving the condition of life, the necessities of life, if I forget my real business, is that intelligence? Therefore it is said duṣkṛtinaḥ. Kṛti means merit. But merit is being utilized for sinful activities.
Take for example the meat-eaters. When man was... The uncivilized man is still there. In the uncivilized way they are living in the jungle. They require to eat something. So they stone over an animal going, and the animal dies, and then they eat. Now instead of killing the animal by stoning, if you have discovered scientific machine in the slaughterhouse to kill the animal, is that improvement? If you think this is advancement, "Now we have discovered very technical machine. Instead of stoning one animal killing, it takes so much time, hundreds and thousands of animals you can kill in one hour," do you think that is improvement? That is going on. They think this is improvement. When we were uncivilized, we were stoning some animal and killing and eating, now we are, business is the same—animal killing and eating. But we have improved the machine how to kill. This is going on. This is going on as advancement of civilization. Hmm? What is your answer? Is that advancement of civilization?
Now you are civilized, instead of killing the animal, you just take milk from it without killing and make so many nice preparations, and that is civilization. But killing is sinful. You have no right to kill any animal, even an ant. Because you cannot give life to anyone. It is nature's law, God's law. So infringement on the laws of nature or God, it is sinful activities. So you are utilizing your merit for this sinful activity. Therefore it is called duṣkṛtinaḥ. Merit is there, but it is utilized for sinful activities. That is defect of the modern civilization.
