Benton was born in Niagara Falls, New York but was raised in Tampa, Florida. It was here on July 21, 1987, after guitarist Brian Hoffman replied to Benton's advertisement in a local music magazine, Deicide was formed. Within days the band, consisting of Benton (bass/vocals), Hoffman, Hoffman's brother Eric (guitars) and Steve Asheim (drums), was named "Amon", after the Egyptian deity. Within a month, Amon had recorded the crude Feasting the Beast 8-track demo in Benton's garage and had started playing the occasional gig in the Tampa area. In 1989, Amon recorded their second demo, Sacrificial, at Morrisound with producer Scott Burns. Benton reportedly stormed into Roadrunner Records' A&R man Monte Conners' office and presented him with the demo, saying, "Sign us, you fucking asshole!" The next day contracts were issued to the band.
Benton is known for his Satanist and Anti-Christian beliefs and views of "today's corrupt religious systems." He is renowned for an inverted cross he has repeatedly branded into his forehead over the years. According to Steve Asheim, this act was likely in response to previous press attention the band received when Brian Hoffman burned an inverted cross into his arm with a cigarette.
Despite having claimed in an interview he shares a "spiritual link" with Lucifer, who tells him "what to say and what to write about," the nature of Benton's 'Satanism' is obscure and a subject of controversy, particularly due to allegations by former Deicide guitarist Eric Hoffman, who dismissed it as insincere and spurious. In early years, Benton was ostensibly a theistic satanist; he implied he had held the belief of the Christian God but worshipped Satan instead. Thus, his beliefs have been questioned by followers of Anton LaVey's Church of Satan, which Benton has blasted on the grounds it is an organized religion, promoting what he perceives to be "Hollywood Satanism".
Arguably, Benton's claims have always been tongue-in-cheek as his purported "Satanism" has since largely been defined as vehement anti-Christian atheism complemented with theatrics suitable for the band. In the July 2008 issue of Revolver Magazine, Benton stated there was no ideological agenda in Deicide and the music was first and foremost.
The self-titled 1990 debut album of his group Deicide featured a song entitled "Sacrificial Suicide", in which Benton was alleged to have claimed that in order to achieve a life opposite that of Jesus he planned to commit suicide at age 33. This claim that he would commit suicide at the age of 33 continued throughout the 1990s. However, he passed that age in 2000 and did not commit suicide. In 2006, he stated that these statements had been "asinine remarks" and that "only cowards and losers" choose to kill themselves.
In the early-to-mid-1990s, Benton was a frequent opponent guest to Christian radio shows, such as Bob Larson's "Talk Back" show. Though a serious discussion rarely took place on the program, the exchanges between the two mainly consisted of taunts from Benton and tongue-in-cheek teasing. Larson continually invited Benton to his talk show, but Benton often declined.
However, Eli Elixir, Satanic practitioner and former singer of American band Satan’s Host declared to webzine Lords of Metal about Benton:
"We have gigged with these guys in the past here in the States, and I can tell you first hand. He is not one who studies the true Satanic, Luciferian ideologies, as with the philosophies, theories and practices. He is more of a bitter bible basher, in his lyrics and mannerisms. There are very rarely any, to practically no Satanic theorems of the Left hand Path Philosophies, let alone incantations and rituals of evoking. He basically just pontificates his hatred for Christianity and its idiocy to those who follow it. There's nothing wrong with that, it has seemed to work for him as with his ranting ways
In 1993, newspapers reported that Benton had expressed an interest in, and participated in, the burning of live rodents such as rats and squirrels. During an interview with NME Magazine, Benton shot a squirrel with a pellet gun: Benton explained it was to prevent any further damage to his electrical system and other contents in the attic of his home where the interview was held. The publicity led to an attempted bomb attack on Benton during Deicide's Legion tour at the International 2 in Manchester, England, by an animal rights organization. Benton was also beaten up in Bradford. A similar attack was attempted at a previous show in Stockholm, where a supposed small fire bomb was set to detonate during Deicide's set. No one was injured, but the bomb damaged the venue. The bomb was reported to be an M-80. The tour was curtailed.
Benton has a vast interest in motorcycles, which can be seen in the music videos for the Deicide songs "Scars of the Crucifix" and "Conviction." He also has two sons, Daemon Michael Benton and Vinnie Benton. Although Deicide is a death metal band, Benton prefers not to use the "death metal" terminology.
