Hate preacher Abu Hamza al-Masri devoted his life to violent jihad, his New York trial heard.
In closing statements to the jury, US prosecutor Ian McGinley said the one-eyed cleric lied on the witness stand, claiming to be a peacekeeper.
"Abu Hamza would have you believe that nothing is at it seems. This man is trying to blame everyone but himself," Mr McGinley said.
"Abu Hamza devoted his life to violent jihad. That was his choice. He spoke about it, he lived it, he was proud of it.
"Fighting, shooting, kidnapping, killing were all mandatory, all justified in the cause of jihad.
"Abu Hamza jumped at every opportunity across the globe to support making jihad. Yemen, Afghanistan, the United States of America were all in the cause of jihad.
"When he spoke about jihad he was not the calm man you saw in the witness stand. He was enraged, loud, screaming, passionate.
"He was his true self at that time. He was not in front of the jury.
"He announced his intentions in public to his followers. In private, he was the boss, the leader of men, who directed his followers to act on his words.
"He said what he was going to do, he wrote about what he was going to do. He did it repeatedly, deliberately, proudly.
"He instructed his followers that jihad fighting was religious war. To quote him, 'One hour of fighting is worth 70 year of prayer.'
"Why do his words matter? Because they match his actions, they match his crimes. He was a man who supported absolute jihad."
The ex imam at North London's Finsbury Park Mosque denies 11 terrorism related charges, including providing a satellite phone to kidnappers in Yemen.
Prosecutors say the former strip club boss had a lengthy call with the hostage leader Abu Hassam just before the abduction, which ended with two British tourists, a Canadian and an Australian dead.
The 56-year-old is also accused of sending Croydon computer student Feroz Abbasi to the Afghanistan frontline, setting up a jihad training camp in Oregon and providing material support to the Taliban and Al-Qaeda.
Hamza, whose trademark hook hands have been removed for security reasons since he was extradited from the UK in 2012, has denied all of the charges.
During the closing statements, assistant US prosecutor Mr McGinley played extracts of Hamza's sermons and TV interviews.
Photographs of Hamza followers including Abbasi, who spent four years in US custody in Guantanemo Bay before being released without charge, were also reshown to the jury.
"Abu Hamza sent Feroz Abbasi to Afghanistan to train to fight with al-Qaeda," Mr McGinley said.
"And where was Feroz Abbasi found in Afghanistan after 9/11? In the middle of a war zone."
Two of the most compelling witnesses during Hamza's five-week trial were Yemeni hostages Mary Quin and Margaret Thompson, who told how they had been used as human shields during the firefight between their captors and rescuers.
"In Yemen four innocent people were killed by the defendant's long-time associate Abu Hassam. In testimony, the defendant said he had warned people to stay away," Mr McGinley told the jury.
Trial: Abu Hamza
"The kidnapping happened five days after the defendant's stepson was arrested in Yemen.
"This was a brutal attack on tourists targeted on a sightseeing tour because they were Westerners. In the defendant's words that was a good thing, that was justified.
"Oregon, Afghanistan, Yemen - these were the defendant's choices.
"Yet when he testified in this courtroom he ran from each of these choices, these decisions that were at the core of his devotion to jihad, saying he was never involved, he got misunderstood, things had been taken out of context.
"Ladies and gentlemen, he lied to you. He wants you to believe he was some sort of peacemaker in Yemen.
"Abu Hamza praised almost every murderous Al-Qaeda attack. He stood up and praised Osama Bin Laden time and time again and he told us in this courtroom that he loved Osama Bin Laden.
"But he would have you believe that even though he loved Osama Bin Laden he never provided material support.
"Abu Hamza would have you believe that nothing is as it seems. This man is trying to blame everyone but himself.
"He even blamed Mary Quin and Margaret Thompson. Why? Because they went on a sightseeing tour in the Yemen.
"He wants you to believe he was misunderstood, that he had no command, his men were free agents.
"We know better, that this is a complete and utter lie. His entire approach to testifying before you is to fool you.
"Abu Hanza is a skilled speaker, he knows how to work a crowd. He is careful with his words.
"The real Abu Hamza wants you to believe it is everyone else's fault.
"I will show you from the evidence that is a complete and utter lie. He was no peacemaker in Yemen, no hostage negotiator."
Mr McGinley showed the jury military-style camouflage uniforms, a gas mask and a knife that had been found at the Bly, Oregon, jihad training camp.
