Allison Mack is issuing a mea culpa just days ahead of her sentencing for her role in a self help group that many perceived to actually be a sex cult.
In her a letter filed in Brooklyn Federal Court, she says that following the teachings of Nxivm leader Keith Raniere is the "biggest mistake and greatest regret of my life."
Page Six obtained a copy of the letter in which the former "Smallville" actress apologized "to those who have been harmed by my actions."
Although Keith Raniere was in charge of Nxivm, Allison was one his top lieutenants and a "slave master" in the group, a group in which women were branded with Keith and Allison's initials (and forced to be "slaves.") The women were also blackmailed into having sex with Keith. Last year, Keith was sentenced to 120 years in prison. Allison's sentencing is set for June 30. She's pleaded guilty to racketeering and racketeering conspiracy charges, including extortion and forced labor.
"I am sorry to those of you that I brought into Nxivm. I am sorry I ever exposed you to the nefarious and emotionally abusive schemes of a twisted man," she wrote in the letter.
The Teen Choice Award winner has been on home confinement with her parents while awaiting her sentence.
"This period of isolation has been the most devastating, but transformative time of my life," she wrote. Home confinement, she continues, has provided the "strength I needed to confront the darkest parts of myself and come to terms with the pain my actions have inflicted on so many people I love."
She adds, "It is now of paramount importance to me to say, from the bottom of my heart, I am so sorry… I threw myself into the teachings of Keith Rainire [sic] with everything I had."
The 38-year-old actress also apologized to friends and family who tried to warn her about Keith and Nxivm.
"I pushed you away and silenced myself toward you when you were trying to save my life. … I lied to you, again and again, in order to protect the delusion I was so deeply committed to believing," she wrote. "The list of those harmed by the collateral damage of my destructive choices continues to grow as I become more and more aware of how my choices have affected those around me. I am grateful that I have made it through this process alive and that I stopped when I was."
