The so-called Green Beret Killer, Army Dr. Jeffrey MacDonald and Scott Peterson (both convicted of killing their pregnant wives) are known to have attracted seriously hybristophilic women.
Even notorious terrorists like Boston Marathon Bomber Dzhokhar Tsarnaev, who along with his older brother murdered and maimed nearly 300 people,
gets love letters as he continues to appeal his death sentence.

In other words, there seems to be no crime horrific enough to repulse those who are obsessed with the need to feel close to heinous criminals.

But why? What drives a person to want to cozy up to someone who has done such horrible things?
What woman would agree to visit with or actually marry a man who can never come home with her?
