Why Did Christopher Scarver Kill Jeffrey Dahmer?

According to his interview with The New York Post, the real Scarver did this too.

On the day of Dahmer’s murder, Scarver, Dahmer, and another inmate named Jesse Anderson had been left unsupervised while they were cleaning bathrooms in the prison gym. Either Anderson or Dahmer poked Scarver in the back, which annoyed Scarver.

Although he didn’t know who poked him, Scarver set his sights on Dahmer, which led to their fateful confrontation. Just like in the series, the real Scarver confronted Dahmer about what he had read about in the clipping.
