Terror groups exploit the weak for suicide bombings

According to  Joshua Sinai, is easier for the terrorist to influence weaker people to do the job as suicide bomber. he also states that they training them and video tape them. He thinks it would be interesting to see if the group behind the Moscow airport bombing are going to post a video of the martyr suicide bumber. I think they influence the people that they know will do the job, either if it is for money or because they're crazy killers. They destroy and kill innocent people because they hate them. They teach people to hate through the use of propaganda in religion, media and even schools. He appeals to our emotions and he uses transfer by discussing terrorism and suicide bombers.
