Personality variables such as extraversion, agreeableness, and neuroticism have also been speculated from twin studies to be about 50% heritable, which can certainly impact the likelihood of certain negative behaviors.

I just think it is valuable to consider the environmental affect on the expression of genetic factors, including those that developed during embryonic development. Fetal alcohol syndrome research, for example, certainly posits a relationship between prenatal development and later behavior.
