DENISE BROWN, who has made it her mission to help victims of domestic violence since Simpson was acquitted of her sister's murder in 1995, was shocked to hear he has recently been signing autographs at horror conventions.
But Brown insists even though Simpson walked free from court a decade ago last Monday (ends03OCT05), he remains a figure of hate to her.
She says, "He's just a murdering idiot. I wish him 17 years of hell because that's what he put Nicole through.
"He may be out free but he's a social pariah. No one is embracing him.
"The anniversary of her death in June is very hard but the anniversary of the acquittal doesn't exist as far as I am concerned.
"But every time he gets arrested or signs autographs at a horror convention, it gives me the opportunity to talk about domestic violence.
"When I heard he was signing autographs at a horror show, I laughed. He is the horror show. He is the devil and he doesn't need to get dressed up for it."
In October 1995, a California jury found Simpson not guilty of murder in the June 1994 slashing and stabbing deaths of his ex-wife, NICOLE BROWN SIMPSON, and her friend RONALD GOLDMAN.
In 1997, a civil court jury found Simpson liable for the deaths and ordered him to pay $33.5 million (GBP18.6 million) in damages to the families of the victims.
