Mohamed Merah , the French  23 year old man who became a terrorist  wanted to "teach France a lesson". because they refused to let  him join the French army so he turned his back to his birth country. He went to Pakistan where he met with the Talibans who put him in contact with jihad trainers to teach him how to use weapons. For me this young man was completely disturbed and lost! We all have the right to express ourselves when we are not happy about something  but i don't think anyone should decide who must  die in this world thinking that it will resolve their problem . I don't want to defend him because I think what he has done was unforgivable  but I can  understand how frustrated someone  can be  who were born and lived  in a country for many years and  to feel  unaccepted by people that they considered as equal  who judged their skin colour or religion  all the time. But this doesn't give one the right to go and kill people so he should be punished  for that.http://www.thedailybeast.com/articles/2012/04/02/mohamed-merah-who-killed-7-in-france-embodied-al-qaeda-s-lone-jihadist-campaign.html
