The need to exchange goods or gain profit induces humans to trade and the difference of goods being exchanged is the basis for human social life. Usury or negation of ownership The reciprocal exchange of two similar goods where the value and object of sale are equal is considered valid in many human societies. Such an exchange may be performed for various reasons bringing about cheerfulness and friendship in the society and resolving the needs of the disadvantaged. This entails no evil.
