A continuation of the previous thread. After discussing the definition of "anti-social behavior" I'll elaborate with more information from the book...
The first signs of altruism and sympathy for others usually appear during toddlerhood, which supplants the infants inborn narcissism. Psychopaths, on the other hand, make it to adulthood without ever developing the capacity for empathy and sympathy. One thing they do well though, is imitating these characteristics.
One thing that comes to mind in cases of children and their behavior is the famous concept of nature versus nurture or genetics versus environment. To put this simply, in cases of children having antisocial behavior tendencies, it's a combination of both.
One thing our professor has stressed is that there is something definitely wrong with these kids who shoot up schools, or grow up to be serial killers: they face and deal with things others have and continue to deal with, certain people just don't react like others when faced with these things. Kip Kindler was 15 when he killed his parents, went into school (the day after being expelled for having a gun in his locker) and shot 28 people, 2 of which died.
His parents were teachers, he grew up in a nice neighborhood, in a nice house, and lived a pretty well-off lifestyle, nothing fancy, more so upper-middle class. We had to watch an hour and a half video on his life and the shootings, and it seems like what our professor said told a lot about this kid, he dealt with things that a lot of normal people deal with (he had trouble in school early, was small and got picked on, got in trouble at school, and got his heart broken), he just couldn't handle these things.
There were warning signs, signs that should have been noticed, he even saw a psychiatrist and was on prozac, but once his parents thought he was good and the psychiatrist said he didn't have to meet with them anymore, his parents stopped the medication. The signs were very clear: he wanted guns, asked for them and eventually got his parents to buy them, he stole CD's from a store and got caught, kicked a kid in school and was suspended for 2 days, he was caught with books on how to make bombs, told his psychiatrist that he made bombs with gas and exploded them in a quarry when he was very angry, and some other minor things like hanging out with the wrong crowd.
It seems that all these cases of kids who shoot their classmates have very clear signs something is wrong with them, yet no one realizes how bad it is, and their parents always think it is just a phase or don't believe it's as bad as it is.
One sidenote on something interesting I learned in class was the difference between a psychopath and a sociopath: A psychopath is someone who disregards laws, rules, morals, ethics, and the common good of society (including their family and friends) and are often serial killers (90% of serial killers are psychopaths), while sociopaths only follow and adhere to the "rules" of his or her "family", for example the Manson family or a Mob family, and outside of their close knit circle they do not care about societies rules or laws.
