How sociopaths are made?

I've been reading Social Intelligence by Daniel Goleman and thinking about how and why I became a high functioning sociopath. Psychologists and scientists believe sociopthy is some combination of genes and environment, which makes sense, particularly in light of recent research suggesting that not only do genes matter, but that the body's varying expression of the genes appears in response to environmental or other factors. As Dr. Goleman says:

If a gene never expresses the proteins that could direct the body's functioning in a given way, then we may as well not possess that gene at all.

If there were some triggering event or environmental force that triggered my sociopathy, I think it was just as likely something that happened to me as a baby than something within my conscious memory. For instance, when I was an infant I had a particularly bad case of colic, a poorly understood condition affecting infants whose main symptom is "frequent, inconsolable crying." According to my parents, I cried incessantly, and according to my medical records I had to go to the doctor for a ruptured navel due to excessive crying. I'm sure my parents did as well as they could, but it no doubt must have been difficult to tolerate such a child, much less nurture it.

Dr. Goleman says that although the brain doesn't reach maturity until 20, the biggest growth spurt is in the first 24 months of life. He also cites a study regarding the importance of the very beginning of a mammal's existence in brain programming:

[A]t least for mice, a vital way that parenting can change the very chemistry of a youngster's genes. [A] singular window in development [is] the first twelve hours after a rodent's birth--during which a crucial methyl process occurs. How much a mother rat licks and grooms her pups during this window actually determines how brain chemicals that respond to stress will be made in that pup's brain for the rest of its life.

The more nurturing the mother, the more quick-witted, confident, and fearless the pup will become; the less nurturing she is, the slower to learn and more overwhelmed by threats the pup will be.

The human equivalents of licking and grooming seem to be empathy, attunement, and touch. If [this research] translates to humans . . . then how our parents treated us has left its genetic imprint over and above the set of DNA they passed down to us. And how we treat our children will, in turn, set levels of activity in their genes. (pp. 152-54)

The book is not all that helpful for sociopaths, and has a low opinion of us generally, so I wouldn't recommend taking the time to read it. But maybe I'll post some other sociopath-specific information I find.
