I can understand who is following the path of devil and creating devilish act on humanity by killing innocent people, womens and kids in the name of Allah. First learn about your prophet. He was a good man untill he turned 40. Then started preaching his own religion and for non muslims their was death other then accepting islam and for those who died for jihad the 72 virgins waiting for them in haven, this is what encouraging them to blow up them selfs to kill others. This is enough to judge who was preaching the devil.
