Mainly naive malleable young men who're easily taken advantage of by religious extremists in just the same way as gangs (drug related or otherwise) draw in new members and even future victims. Not so very different from the sort of controlling, abuse employed by the paedophile gangs in enticing vulnerable young girls into their networks and convincing them, over a period of time, to do things they'd never have dreamt of. The only motive these young terrorists have for what they do is the motive seeded in their minds, sometimes over many years, by those who so cleverly exploit them which include religious leaders they've been taught to look up to.
