Believers' Holy Fight of Faith A central purpose for several of the world's major religions, is to expand its global group of believers, in competition with other worldviews. It cannot then be ruled out, that in some cases this labour of salvation has to be carried out through force. In fact, so far holy warriors of faith have killed off at least 130 million people that had the wrong belief. - so, if  your  religion's followers should feel like punching people in the face, that's totally fine!
