Evan Peters has played many characters on "American Horror Story." From a ghost in a murder house to a murderous spirit in a hotel to a frat boy zombie, he has had his fair share of scary and disturbing characters. But his latest project, "Monster: The Jeffrey Dahmer Story," may provide his scariest role yet. Peters will be playing the notorious serial killer and has recently spoken about the difficulties of taking on the part as well as the rule Ryan Murphy, the creator of the show, set to make sure the production was respectful. Taking on a role like this requires a lot of care because, as Evan Peters says, it’s important to respect the victims and not sympathize with the killer. He has spent a lot of time figuring out how to play Jeffrey Dahmer and said it was incredibly difficult. In an interview with Ryan Murphy Productions he elaborated on why such care needed to be taken.
