Being in the Pistols had a progressively destructive effect on Vicious. As Lydon later observed, "Up to that time, Sid was absolutely childlike. Everything was fun and giggly. Suddenly he was a big pop star. Pop star status meant press, a good chance to be spotted in all the right places, adoration. That's what it all meant to Sid." Westwood had already been feeding him material, like a tome on Charles Manson, likely to encourage his worst instincts. Early in 1977, he met Nancy Spungen, an emotionally disturbed drug addict and sometime prostitute from New York. Spungen is commonly thought to be responsible for introducing Vicious to heroin, and the emotional codependency between the couple alienated Vicious from the other members of the band. Lydon later wrote, "We did everything to get rid of Nancy.... She was killing him. I was absolutely convinced this girl was on a slow suicide mission.... Only she didn't want to go alone. She wanted to take Sid with her... She was so utterly fucked up and evil."
