I would like to point out that the poll is a fixed question. "Can" as used in that sentence is an absolute. All things are possible, some things are more plausible. I voted yes because I am sure that you "can" with enough research put together a link between the two.
That said, I think you have to ask yourself why you seek a one size fit all answer to a complex social problem. There are those in this world that feel that morality is bestowed upon us from generation to generation through ancient rituals and laws that are suppose to govern our conduct. Science has concluded that at the age of five most children begin to rationalize. If you were to ask a sample of children ages five to eight questions about morality they would almost all come to the conclusion that hurting others is wrong, breaking rules that do not harm others are more flexible. When you break our understanding of morality down to its basic forms you are left with some variables. Morality is rationalized by each person based on their experiences, morality is governed by the traditions we are brought up with and morality is directly related to the amount of knowledge that person has obtained about the world around them.
To learn more about this I highly recommend the book "The Righteous Mind" by; Johnathan Haidt.
When you have an understanding about the origin of morality you can begin to discuss other factors that play into the reasoning behind the aggression.
From a young age we cart our children off to a place that most hate. The buildings are massive catacombs full of hostile environments and small class rooms. There the child is criticized for every assignment they complete and forced to take greater amounts of work home to monopolize every minute of their lives. Forced to obey even the most ridiculous authority, there is no room for questioning the curriculum and even if you begin to understand a subject you are screamed at to move along to the next subject at breakneck speed because time is a stringent element of manipulation. You have no rights, no amendments, you will be cussed at and worse. The administration does not care for you and the moment you fail to curtail your childish twitching you are forced to swallow pill after pill of mind altering substance proven in every modernized society to be extremely harmful for growth and they ultimately force the user to become dependent on substances for the rest of their life to balance the chemicals in their brains.
I highly recommend that you seek out, "The War on Kids."
There will never be a one word answer to the problems that dog the most advanced and complex species to ever roam the planet. We have created an existence for ourselves that can create either the worst of monsters or at best the worst of people.
