Speaking from a Christian viewpoint since I'm assuming youre coming from that background as well...it's not Islam.. it's sin and the total depravity of the human heart. Even if it's might be easier to use Islam to justify slaughter than Christianity or Hinduism, the truth is you have people using religion of any sort to justify their sin. See Westboro Baptist, Crusades, etc See treatment of untouchable castes etc It's a heart problem. Not a religious one. Though as a Christian I'd argue that the truth of Christianity is the only one that provides the solution to that issue.
