In a letter obtained by The Hollywood Reporter, the 38-year-old Smallville alum addressed "those who have been harmed by my actions," writing, "It is now of paramount importance for me to say, from the bottom of my heart, I am so sorry."
"I threw myself into the teachings of Keith Raniere with everything I had," she explained. "I believed, whole-heartedly, that his mentorship was leading me to a better, more enlightened version of myself. I devoted my loyalty, my resources, and, ultimately, my life to him. This was the biggest mistake and regret of my life."
In addition to the direct victims, Mack also acknowledged "those harmed by the collateral damage of my destructive choices." She maintained she would dedicate the rest of her life to making proper amends and becoming a more compassionate person.
"I am sorry to those of you that I brought into Nxivm," she wrote. "I am sorry I ever exposed you to the nefarious and emotionally abusive schemes of a twisted man. I am sorry that I encouraged you to use your resources to participate in something that was ultimately so ugly. I do not take lightly the responsibility I have in the lives of those I love and I feel a heavy weight of guilt for having misused your trust, leading you down a negative path."
Mack's letter was accompanied by a memo from her attorneys, which included sentencing guideline recommendations.
They asked for no jail time given that she's recognized she "committed grievous wrongs" and has "earned her punishment." They also argued that Mack has "publicly denounced Raniere (and her own prior association with Raniere) in the strongest possible terms."
"That is made clear by Ms. Mack's plea allocution, her decision to cooperate completely and fully with the government, and is further underscored in her letter to this Court as well as her efforts to demonstrate her remorse to the public generally and more specifically to those she harmed," the memo stated. "There is thus no need to impose an additional sentence of incarceration on Ms. Mack to achieve specific deterrence."
As Radar previously reported, prosecutors asked U.S. District Judge Nicholas G. Garaufis – who is presiding over Mack's case – to go easy on her sentencing after her cooperation with investigators helped them convict Raniere.
Most notably, she provided the feds with an audiotape of a blood-curdling discussion she had with the sex cult leader about how to brand his "slaves" with his initials.
In addition, Mack – whose role has been identified as the "master" of the group – turned over information about crimes committed by other group members as well as provided emails and other documents.
She also told investigators that Raniere would ask for nude pictures from the women she had not only recruited to join the group but also encouraged to have sex with him.
In April of 2018, the FBI arrested Mack in Brooklyn, New York, on charges of sex trafficking, sex trafficking conspiracy and forced labor conspiracy. She pled guilty to racketeering charges one year later.
Last October, Raniere was sentenced to 120 years behind bars after being convicted of seven felonies.
If Mack's sentencing goes as the cult leader's did, she will most likely receive the maximum jail time: 40 years.
She will learn her fate on June 30 at the Jack B. Weinstein Ceremonial Courtroom in Brooklyn.
