kolbergs moral development theory
our idea of right and wrong develop through a series of levels and stages from childhood to adulthood.
post conventional (adulthood): principle and social contract
conventional (8-13): law and order morality and good boy/girl attitude
pre conventional (3-7): self interest and avoid punishment
criminals moral development is stuck at a less mature level and they solely think if their actions will lead to reward or punishment, rather than its effect on others
