New details about the extremist views of convicted killer Dylann Roof have emerged in the form of a letter he reportedly wrote in response to a reformed white supremacist interested in reaching out to him.

The initial letter presented an olive branch to Roof, according to the New York Daily News, but was met with mockery by the unrepentant shooter responsible for nine deaths at a predominantly black church in Charleston, South Carolina.

Though he has complained about the accommodations behind bars, Roof previously declared that losing his freedom was “worth it” in the pursuit of his racist agenda, as reported by the Washington Post.

“I would like to make it crystal clear, I do not regret what I did,” Roof wrote at the time. “I am not sorry. I have not shed a tear for the innocent people I killed.”

His subsequent letter to the former racist revealed he was still clinging to the hate-fueled ideology that sparked his violent church massacre.

“You couldn’t handle the mental stress that comes along with white nationalism, so you took the easy way out,” he wrote to the reformed radical.

Roof added that what he found “so disgusting” was not that the man severed ties to the white nationalist movement, but that he “decided to devote [his] life to undermining [his] own race.”

The screed continued with Roof asserting that he didn’t know how the former racist could live with himself.

“I hope you know that you are 100 times worse than the Jews you’ve surrounded yourself with,” he wrote.

Christian Picciolini, the one-time neo-Nazi who reached out to Roof earlier this year, shared his experience in a recent “60 Minutes” interview, according to the Post and Courier.

He now works with police in an effort to provide active white supremacists a way out of the deadly movement. The letter he received from Roof, however, suggested he would not make a good candidate for any type of reform.

“That tells me he is completely indoctrinated by these alternative set of facts … pushed by a movement that puts all the blame on Jewish people,” Picciolini said.
