"I think that these guys do not become radicalized because they become more and more religious. It is not religious radicalization that leads to political radicalization. When they became radical, they are religious. They frame their wrath in a religious narrative. They think they will go to paradise. It is Islamization of radicalization. I think Islam is the framework of the radicalization; it is not the primary cause. What I am saying, which there is a lot of misunderstanding about: It is not because they pray more and more, or go more and more to a mosque, that they become radicals. When they became radicals, they choose the religious narrative and believe in it. These guys are not Salafi. The idea that this is the Salafization of Islam does not make sense because their approach to salvation is not the Salafi approach. The Salafis do not believe in suicide. They think that suicide is a sin against God, like the Jews and the Christians. If you kill yourself or put yourself in a position where you will necessarily be killed, you preempt the will of God. But in the mind of the suicide bombers, the idea is that you don’t need to be a good Muslim, you don’t need to pray five times a day, you don’t need to go for hajj. If you make a supreme sacrifice, you will go directly to paradise and there is no need to be strict believer." (thanks Nabeel)
