Of course there is! But its not just one. There is the one called "MAOA" gene, but scientists are studying others variables like exposure to violence and others genes. They associated this gene with agressive behavior, for criminal profiles too. its like the "fight or flee" behavior, some people will likely fight everytime in danger situations. But you dont know until you are in a danger place like a violent community or at war huh?
Many scientist today study aggression as some type of disorder which is absolute nonsense (In some rare cases it is disorder) . That is very important survival mechanism and people have to be aggressive (not necessarily physical violence) in order to survive are to be successful. Then again, be too aggressive or in ways they your "herd" does not approve and you will be expelled from the herd.
What I meant to say with my previous post is that everyone of us is capable for violence if we are puted under right condition.
