It is a normal component of adolescence to want to set their own limits, to challenge authority, and so on. All young people go through it: pushing the boundaries, establishing their territory, feeling that they are in full possession of their faculties, wanting to make their own decisions. That is fundamental to human behaviour.
In terms of the level of moral judgment, we have specialized clinics, for example in-patient clinics, that regularly use tools to assess young people's level of moral judgment, their level of interpersonal maturity. We see that it is often below the young people's chronological age. In reality, a 17-year-old or 18-year-old sometimes has the reasoning ability of a child of 10 or 12. The young person's age and appearance does not reflect what they are, or their psychological competencies or reasoning ability.
