Can the theories of biological predisposition to crime be reconciled with rehabilitation concepts?
Yes, theories that hold that people can have biological predispositions to crime can be reconciled with the idea of rehabilitation. The reason for this is that biological predispositions are only predispositions. They are not factors that can absolutely determine whether a person will or will not commit crimes.
Biosocial theories of crime are not deterministic. They do not say that you are absolutely 100% guaranteed to become a criminal if you have a certain gene. Instead, they say that you are more likely to commit crimes if you have certain genes. This is a big difference. These theories also hold that environment matters. For example, a person who is predisposed to crime can be prevented from committing crimes if he or she is brought up in a good environment. This is where rehabilitation comes in. If a person who has already committed a crime can be exposed to more opportunities and a better environment, they can overcome their predisposition towards committing crimes. Rehabilitation can expose them to these things.
Therefore, we can see that rehabilitation and biosocial theories of crime are not at all incompatible with one another.
