The brother of the Unabomber has spoken out, saying that knowing that the alleged UnitedHealthcare CEO killer read his sibling's manifesto "gives me a great deal of personal pain."
David Kaczynski, the brother of Ted Kaczynski, also known as the Unabomber, said that his sibling's actions are "like a virus," in an interview with NBC News. He said that while the Unabombers words may not sound so wild, but "his behavior, I believe, is the behavior of a lunatic."
