I disagree with your opinion, but testosterone is a thing which should be considered in that extreme violence, but not the whole, just a part, there are numerous reasons for that shooting respectively, it should be a child abuse, indiscrimination by society, social ignorance, poverty, or might be more consider the fact of psychological illness, but how that person involved in that event, its not easy to make a judgment, there will be held
a deep investigation or to involve the person in many dialogues and assessment, but your writing was much impressed, i must appreciate.
Thank for your contribution....
