What happens when you marry a seriel killer? What sympathy do you get when you break down the door to marry a seriel killer?

  Actually, many serial killers that were married appeared very normal to their spouses.  A few that come to mind are:  Ted Bundy, the BTK Strangler and Gary Ridgeway (the Green River Killer) to name a few.   Usually, these types of killers fulfill some secret fantasy which they keep separate from their "normal" lives, which is why most of them have families and jobs and seem just like everyone else.    So, to answer you question Spears, most wives are shocked when their serial killer husbands are arrested, as they were utterly clueless.
