dont you think all that massive murders is some kind of conspiracy? is just crazy that somebody enters a place with a gun and start killing innocent people... is just madness
nah... the aggression is taught to us at a young age through movies, games, stories, books... we all have a choice, some of us choose to walk the same as our past and dont know better
aggression is taught, or should i say exploited more than other emotions, non the less emotions are another form of energy and we are given the choice on how to transfer that energy.
