So has the Chattanooga Jihadi.
He realized he was a loser. He had failed at life, and failed Allah. He felt like he was in a prison.
Jihad was the only way to redeem himself:
Abdulazeez then discussed the Sahaba — the companions of the Prophet Muhammad — and how they served their faith by bringing it to the world, sometimes through jihad.
"Did you ever notice that in one certain period towards the end of the lives of the Sahaba (RA), almost every one of the Sahaba (RA) was a political leader or an army general?" Abdulazeez wrote. "Every one of them fought Jihad for the sake of Allah. Every one of them had to make sacrifices in their lives." ("RA" is a term of reverence meaning "May Allah be pleased with him or her.")
Abdulazeez praised the Sahaba further.
"They were very simple in the lives that they led and they were comprehensive in their understanding of Islam and applied what they knew," he wrote. "And that's why they are considered to be the best generation that ever lived. After the prophets, they were the best human beings that ever lived."
He concluded by asking Allah to help believers follow the example of the Sahaba.
"We ask Allah to make us follow their path," Abdulazeez wrote. "To give us a complete understanding of the message of Islam, and the strength the live by this knowledge, and to know what role we need to play to establish Islam in the world."

He wanted to be like the Sahaba, and help to establish Islam in the world.
But, hey, that's nothing at all like wanting to start a race war.
