That's a very true statement and I think it highlights why the criminal justice system is making a huge mistake when handing out punishment and sentences leading to 25 years to life in gaol for serious crimes for such offenders. Science has proven brain is still forming and the things you disussed are true. Seems our thirst for revenge and the systems need for validation leads to society being just one -blam!-ed up situation following another. Guess someone needs to make sure the privatised prison system can earn a profit...
