There is clearly a genetic component to sociopathy, and is is not merely epigenetic,
The environment cannot create physical differences in the brain from birth,
unless we are referring to an environment filled with toxins,
in which case, all babies born in that environment would share the same physical differences.
The environment only effects the actual degree of expression of sociopathy, not whether it exists in the first place. Most sources cite about a 50/50 influence for genetics/environment. The brain of a sociopath is structurally different from normal humans, and is structurally different in the same way for all sociopaths studied. Those differences have been seen no matter how young the sociopath studied was. It is clearly a genetic difference.
Sociopaths are a predator subset of the human race, evolved to practice predation socially.

Sociopathy is not purely genetic - it is cultivated, nurtured and created by our corporate society. ...Virtually any genes' protein products can be modified by numerous environmental influences - it's a HUGE mistake to assume a mutant protein implies a mutant gene.
But if the genetic load is too high, no amount of good rearing will change the outcome: you have a full-blown sociopath on your hands no matter what you do, how they are treated, what they eat, or who they play with.
Some are simply born that way, and therefore it implies that genetics is truly in play, not merely society.
if the genetic load is too high
Genes don't work that way: no amount of environmental influence will change the color of your hair, eyes, or skin.
VIDEO: Epigenetics
Environmental factors can alter the way our genes are expressed, making even identical twins different.
Once nurture seemed clearly distinct from nature. Now it appears that our diets and lifestyles can change the expression of our genes. How? By influencing a network of chemical switches within our cells collectively known as the epigenome.
Epigenetic regulation of gene expression: how the genome integrates intrinsic and environmental signals
……differences in gene expression arise during [cell] development and are subsequently retained through mitosis. Stable alterations of this kind are said to be 'epigenetic', because they are heritable in the short term but do not involve mutations of the DNA itself. Research over the past few years has focused on two molecular mechanisms that mediate epigenetic phenomena: DNA methylation and histone modifications. ……Epigenetic effects by means of DNA methylation have an important role in development but can also arise stochastically as animals age. Identification of proteins that mediate these effects has provided insight into this complex process and diseases that occur when it is perturbed. External influences on epigenetic processes are seen in the effects of diet on long-term diseases such as cancer. Thus, epigenetic mechanisms seem to allow an organism to respond to the environment through changes in gene expression.
….For decades, scientists and doctors assumed that cancer was caused by damage to some critical stretch of DNA within one's genome. But recently, a more complex picture has emerged, one that shows that some cancers are caused by epigenetic changes—tiny chemical tags that accumulate over time and can turn genes on or off. Unlike genetic damage, epigenetic changes can sometimes be reversed…..
EPIGENETICS 101
…..skin and eyes and teeth and hair and organs all have exactly the same DNA. You cannot genetically tell my skin from my eyes or my teeth. Yet these are very different cells. They behave differently. And that behavior remains the same for as long as I live.
That difference, not being genetic, has been termed epigenetic. It is a difference that is not due strictly to genetic changes but to the way we utilize these genes. And so the same process that can cause such a profound difference that one tissue looks like skin and one tissue looks like eye could actually cause less profound changes….

There is clearly a genetic component to sociopathy, and is is not merely epigenetic, as that would imply that everyone has an equal chance of bing a sociopath, which is provably false.
Why are you fighting the concept so hard?
"Genetic load" refers to much of a genetic inheritance is received from parents. ….In the latter case you are nearly 100% certain to give birth to a sociopath.
War Against the Weak
War Against the Weak is the gripping chronicle documenting how American corporate philanthropies launched a national campaign of ethnic cleansing in the United States, helped found and fund the Nazi eugenics of Hitler and Mengele — and then created the modern movement of "human genetics."
Genetic load
The concept was first formulated in 1937 by JBS Haldane, independently formulated, named and applied to humans in 1950 by H. J. Muller, and elaborated further by Haldane in 1957.
If my hair is black, my wife's hair is black, and everyone's hair on both sides of the family has been black for generations, and my wife gives birth to a blond-haired kid, then I'm having a talk with her and my blond-haired neighbor.
As far as focusing upon politicians and police, those are the law-makers and law-enforcers. Clean those two up, and it will be far easier to control the corporate side.

Hmm. This discussion is NOT about whether or not sociopaths exist and are dangerous. It is about whether or not sociopathy is genetic - "Should screening for genetic sociopathy be mandatory..."?
Too many people are on the "it's genetic" bandwagon when very, very few traits, diseases or anything is genetic - the only scientists who make such claims are those whose livelihoods depend on maintaining the fiction - the only politicians who push it are those who are looking to cut healthcare and other costs through euthanasia. Most traits result from an extremely complex interaction between genes and environment. And we simply do NOT know enough about the process to start "screening for genetic sociopathy."
Ed to add - also, I take GREAT exception to the exclusive focus on politicians and police - when our world's business model and corporate laws literally mandate sociopathy.
What's that about?

Yawn, You read but do not comprehend. It was a thinly veiled accusatory statement on my part.
What I meant is, a certain percentage of sociopaths and psychos are in this very thread.
