This doesn't occur before the formal operational stage.
According to Jean Piaget, a Swiss psychologist, every person goes through 4 developmental stages: 
- sensorimotor : birth - 24 months
- preoperational: 24 months - age 7
- concrete operational: 7 - 14

Ethics refer to moral principles that guide how people act or do things.

Organizations have core values and code of ethics that guide their operations. To make an ethical decision as a member of an organization, one must have an understanding of the core values and code of ethics of the organization, and should be able to combine these with his or her own personal values.
