"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."
