How severe the penalty is depends on how much the crime hurts others. Murder, for example, hurts others very much, therefore, the penalty is most severe. Penalties also protect the community from harm in cases where a person who threatens the safety or wellbeing of others is removed from the community. Desire and Opportunity Penalties, however, have never been very successful in making people change their behaviour. Personal development and personal growth is necessary in order to change behaviour.
Personal development is the growth of a person in the four aspects of their nature.
Crime prevention through personal development is an effort to change what is going on inside a person to make their outward behaviour change. The focus of personal development within the community, can be on the desire of the person to commit the crime. The community can do this by providing alternatives - other ways and other things for a person to do. They can introduce a new commitment in people to doing good things for their people. By removing the desire of individuals to commit crime, crime will be prevented.
