"bad" & "good" are relative terms. In some societies, the willingness to fight & kill are considered to be virtues, and at one time were true survival characteristics......I am more & more coming to the suspicion that a lot what WE consider to be anti-social behavior may be a combination of testosterone, genes AND social conditioning.

People 'tend' towards timid or agressive, but can be eased into more 'middle of the road' behavior, with conditioning and luck.

You all know someone whose kids simply are 'different' from their parents...or from their siblings. One will be quiet & calm, one will be a holy terror.

I am reading more & more articles which point to discoveries in DNA, etc. that support this. It doesn't change the fact that we need to study and teach and try to instill 'goodness' in people, it merely indicates that we may have more problems than we realized...
