Although originally credited under the pseudonym John Jay Smith, it was later confirmed that the 'Thriller' singer did voice the character.
Michael has been accused of child sexual abuse and Al believes he used the fact that he appeared in the show "to groom boys".
He added: "I don't believe in going through and making judgments on every guest star and saying 'this one was bad, that one was bad,' but the episode itself has a false purpose, and that's what I object to about it now ... I think it was part of what he used to groom boys. I really don't know, and I should be very careful because this is not something I know personally, but as far as what I think, that's what I think. And that makes me very, very sad."
In Dan Reed's 'Leaving Neverland' documentary, Wade Robson, 36, and James Safechuck, 40, both allege that Michael sexually abused them when they were children and would stay over at his Neverland Ranch.
Wade - who testified under oath in Michael's 2005 child sex abuse trial that the musician never abused him - claims that he was molested by the King of Pop from the age of seven until 14. James - who previously testified on Michael's behalf when he was accused of sexual abuse in 1993 - claimed he was abused from the age of 10 until he reached puberty.
The Michael Jackson estate has hit back at the allegations branding both accusers "perjurers" and "admitted liars".
