Never before in the known history of the planet has any land been such a "melting pot" of differing strains of DNA as the US. People from almost every geographical region of the planet interbreed here, and have been doing so for hundreds of years.
mtDNA is passed from mother to daughter
YDNA is passed from father to son
Autosomal DNA is passed 50% from the mother and 50% from the father. Siblings get different mixes of their parents autosomal DNA. Meaning your sisters and brothers did not inherit the same mixes of DNA from your parents that you did. And none of your siblings have the same mix of autosomal DNA that each other does. Every child is different, regardless of the genetic makeup of the parents.
Anyway, could the rapid and repeated mixing of different autosomal DNA that originated in so many different geographical areas be responsible for causing genetic "wiring" malfunctions in certain people's brains when they get a certain autosomal mix?
I don't believe anything near like this long term sustained amount of mixing so many varieties of autosomal DNA at such a rapid rate as ever been done before.
If mutated autosomal dna can cause disease, why can't it flat out cause a propensity toward violence, or a propensity toward violence that can be triggered by stress or other environmental factors in certain individuals with the gene or genes that cause an environmentally triggered violence reaction?
Mother: Her father was Scottish, German, Romanian, and Russian. Her mother was Finnish, Italian, Greek, and Jewish.
Father: His father was Irish, Basque, Serbian, and Japanese, His mother was Native American, French, Estonian, and Tunisian.
Child: a wild mix of a whole bunch of different autosmal dna from all over the place, 50% of which comes from the mother, and 50% of which comes fro the father. Then the offspring with the wild mix of autosomal DNA mates with another offspring with a different wild mix of autosomal DNA, has offspring, and on and on and on.
And this kind of thing has been going on for hundreds of years in the US, and is diversifying exponentially each generation. And I don't believe anything remotely like this has happened before in human history.
No one can possibly know what all the potential effects of the different autosomes are, and how they could affect the human body, and our national population is growing rapidly, so the expression of a "wiring malfunction", a "violence gene" would be much more widespread today than it was 40 years ago. Canada is not really comparable, due to far less mixing and population, so there's nowhere in the world except for the US that has ever experienced this phenomenon.
Again, don't quote me on this, it's just pure speculation, an outside the box idea to consider.
