Sean was born and raised in Long Island, New York. He grew up in a lower-middle-class family in a suburban neighborhood. His interest in hip-hop started when he listened to his older brother's hip-hop tapes, featuring artists such as EPMD, N.W.A. and Black Sheep when he was a child. When Sean was in his early teens, he became interested in graffiti and writing his own lyrics.
Diabolic was a street battle legend on Long Island, New York, developing his skills in record stores throughout Nassau and Suffolk Counties. In late 1999, he took his talent to the New York City underground and made a name for himself in a number of high-profile battles in the legendary New York City venue the Wetlands.
In 2003, Immortal Technique was touring nationally and supported him. Sean was working on his debut album entitled Liar & a Thief and found a producer in Vancouver named Engineer.

On February 10, 2012, Diabolic released a diss track to Tyler the Creator over the instrumental of Tyler's own Yonkers. The track was a response to the title track of Goblin, where Tyler mentions Immortal Technique.
In 2016, a feud was ignited between Diabolic and fellow New York rapper Talib Kweli. After a back-and-forth on Twitter in April in which Diabolic accused Kweli of making generalizations, Kweli penned an article in May titled When 'White Fragility' Affects Rappers, in which he discussed his views on white rappers and referenced Diabolic. In June, Diabolic released a diss track aimed at Kweli titled "IneKwelity."
