" While humans have the propensity to develop a suite of prosocial behaviors, they are also capable of developing antisocial behavior, engaging in substance abuse, experiencing depression, and bearing children at an early age...Young people who develop aggressive behavior tendencies are likely to develop problems with tobacco, alcohol, and other drug use; to fail academically; to have children at an early age;
and to raise children likely to have the same problems. "
