Bryan Cranston once considered murdering a girlfriend, describes graphic details

Breaking Bad‘s bad boy Bryan Cranston revealed that he has a dark side to his real personality. He may not be Walter White, but he’s had some sinister thoughts in the past. Bryan covers the latest issue of GQ, and in the feature story he talks about the matching Breaking Bad tattoos he got with co-star Aaron Paul, getting into character as Walter White, the end of the series, and some violent urges towards and ex-girlfriend.

When asked by GQ if he believed in evil, Bryan answered that he did, and that he believed it was in every person right next to the good.

“I had one girlfriend I wanted to kill,” he reveals. The girl was a lady with substance abuse problems he dated after his first short marriage. According to Bryan she stalked him, following him from L.A. to New York when he relocated to work on the soap opera Loving. She left messages on his answering machine saying “I’m gonna kill you. I’m gonna cut your balls off. I’m gonna have your dick sawed off.”

When she finally showed up at his apartment knocking on the door, Bryan says he “envisioned myself killing her. It was so clear. My apartment had a brick wall on one side, and I envisioned opening the door, grabbing her by the hair, dragging her inside, and shoving her head into that brick wall until brain matter was dripping down the sides of it. Then I shuddered and realized how clearly I saw that happening. And I called the police because I was so afraid. I was temporarily insane—capable of doing tremendous damage to her and to myself.”
