Torah, Deuteronomy 24:7: If a man is discovered kidnapping any person from among his brothers, of the children of Israel, and treats him as a slave and sells him that thief shall die, so that you shall clear out the evil from among you.
This is absolutely forbidden and obviously can not happen because of the principle “love your neighbour as yourself.” And among the nations of the world, people were kidnapped at all times.
The Torah speaks about inner attitude: you can not use your uncorrected or corrected desires egoistically.
For example, if you’ve achieved certain success in working on yourself and suddenly egoism is manifested in you and says: “Let’s turn whatever you succeeded in into a business, or a pleasant pastime. You deserved it,” then by this, you kill everything you did.
This is called “to kidnap your brother,” and to sell him. If your egoistic desire wants to work within you this way, you must destroy it.
