Every man has good people bad you, I see many people also kill the barbaric but they are not Islamic, and the war for what only they understand.
It is not Islam that kills one another, it is the majority of Islam.
Islam, as well as Buddhism or Christianity, advise people to live better. Those who are terrorists, the persistent warfare of the radical Islamic organizations. The majority of Muslims are just like ordinary people.
No religion is bad, only believers for the sake of privacy want to borrow the name of religion to do bad.
