This is truly hijacking a religion in name of god. This sick people are doing this to humanity .. root of the problem is in name of power certain individual or groups recruit vulnerable people who r left out and feel hopeless .. i think addresssing that would be the way to eliminate the problem... human mind is already vulnerable. We have so many unanswered questions.. these guys probably will test the mind asking question that r uncomfortable like death meaning of life and so on and get people brain washed .. removing online propagenda news and fake news is also a top priority so people do not fall prey to this
