What if You Were to Kill Your Wife?

About midway through the movie, i started getting just inundated with violent thoughts. What if i were to brutally stab someone, or shoot some one, or harm my wife? Now s had never had violent thoughts like this before and they were very disturbing. He couldn't get it out of his mind, stabbing her, cutting down her, torso blood and guts all over. The thoughts became so overpowering that after the movie ended he went into his bedroom and just curled up in a ball.
