A US teacher claims to have joined terrorist group Islamic State out of 'curiosity' and says that executions and crucifixions didn't particularly 'bother' him.
Warren Christopher Clark, 34, spent more than three years teaching English for ISIS witnessed the group's brutality.

But in an exclusive interview he explained to NBC News: "I'm from United States, from Texas, they like to execute people, too."
He was captured earlier this month in Syria by US-backed Kurdish forces but admits that he doesn't regret the time he spent working alongside the terror group.
Speaking of why he went to work there, he said: "I wanted to go see exactly what the group was about, and what they were doing.
"I wanted to learn more about the ideology. I'm a political science major, global business minor. I like politics. I like travel, world events. That's what I wanted to do."
The former substitute teacher from Sugar Land, Texas, is adamant that he never fought alongside ISIS but says that led to him being detained almost a dozen times.

According to Clark, each time he was held ISIS let him go and he suffered no abuse at their hands.
Last year NBC reported that Clark's CV had been found inside an Iraqi house. Using the alias Abu Muhammad al-Ameriki, the cover letter read: "I was born and raised in the United States and have always loved teaching others and learning from others as well.
"My work background is largely in English and I consider working at the University of Mosul to be a great way of continuing my career."

Speaking of his experiences, Clark explained that although never involved in the fighting, there were reminders all the time.

"It was a place that was constantly being bombed," he said. "You were always on edge. Day and night, just bombs and airstrikes.
"You sleep in the middle of the day. I spent most of my time living in a mosque. I just remember every day hoping not to get bombed."
