Mosab Hassan Yousef, the son of one of the group's founding members has renounced Islam, Hamas and all that is associated with it.
Yousef, son of Sheikh Hassan Yousef, is openly condemning Hamas (a group he once willingly belonged to) and speaking out against the terror that Hamas is and has been doing against Israel.
"There is no chance. Is there any chance for fire to co-exist with the water?" said Mosab Hassan Yousef, the son of one of the group's founding members.
Yousef added: "It's not about Israel, it's not about Hamas: it's about both ideologies."
What brought him to this point? What was the driving force behind this change of heart?
Yousef said he was indoctrinated at an early age to use violence to challenge Israeli control in the region. As a teenager he moved up within the organization and became the leader of the radical Islamic Youth Movement that fought Israeli tanks and troops in the streets, celebrated suicide bombings and recruited young men to the cause.
Yousef, 30, said he realized the true nature of Hamas and radical Islam during a stint in an Israeli prison. He renounced his Muslim faith, left his family behind in Ramallah and converted to Christianity.
"Islam is not the word of God," said Yousef. "If you want to be offended it's your problem. But you know something? Go study. Think for a second that I might be right. So wake up, look at your path, see where you're going. Are you really going to heaven with 72 virgins after you kill yourself and kill another 20 people?"
Yousef has sought asylum in the United States and now attends an evangelical Christian church in San Diego, Calif.
"The Hamas leadership, including my father, they're responsible; they're responsible for all the violence that happened from the organization. I know they describe it as reaction to Israeli aggression, but still, they are part of it and they had to make decisions in those operations against Israel (for) which there was the killing of many civilians."
They are part of it was his direct quote. This and the rest of the interview with Yousef will be seen on Fox News' Escape from Hamas which airs Sat at 10p, with repeats at 1am and 4a, EST, and Sun at 9pm, with repeats at 12 midnight, 2am, EST.
