The controversial fighter was talking a week after finally regaining his British boxing licence.
The 29-year-old Zimbabwe-born fighter lost his licence after his world title opportunity against WBC title-holder Vitali Klitschko in Munich just over a year ago turned into a weekend of chaos and shame.
Chisora slapped his opponent during the weigh-in, spat water in the face of Vitali's brother and cornerman Wladimir before the bout and brawled with compatriot David Haye at the post-fight press conference.
The series of incidents led to him having his BBBoC licence being withdrawn on March 14 of last year, and 'Del Boy' has not competed since a fifth-round stoppage defeat at the hands of Haye at Upton Park in a main event licensed by Luxembourg's boxing federation.
"Boxing is dead and you need people like me to bring it back up," Chisora told BBC Five Live.
"Someone has to take the bad role and as long as people are tuning in and watching the sport that I love, I don't mind."
Chisora will make his return to the ring on Saturday 20th April at Wembley Arena in a 10-round international contest. The card also features WBO light-heavyweight champion Nathan Cleverly and Commonwealth super-featherweight champion Liam Walsh.
