WHY did Lawrence Singleton dismember 15 Year Old Mary?

Mary Vincent was a lovely, young girl of 15 who lost both her hands because a man three times her age decided to cut them off after having raped her. What had she done to deserve that? NOTHING, except maybe being a little naive and too trustworthy when she climbed into his truck, attempting to hitchhike from Las Vegas to California. After this attack on the young teenager the attacker, Lawrence Singleton, left her for dead, even though she hadn't died, but only fainted. After coming to she managed to stumble away from the cruel scenery, holding her stumped arms up to keep the blood from gushing out. Luckily enough she met two women who helped her get to a hospital. After being attended by doctors she told the police what had happened to her and who did it. Contrary to Lawrence Singleton's belief in his ability to escape the law he was soon found and arrested as his neighbour recognized him from Mary's description of him.

Lawrence Bernard "Larry" Singleton (July 28, 1927 – December 28, 2001) who became nicknamed the "Mad Chopper" in the media, was an abominable American criminal, but behaving well while in jail he only served eigth years of his fourteen years sentence before being released. Sadly enough that was what gave him the chance of committing another crime, this time both rape and murder of a lovely, young mother of three kids, Roxanne Hayes. The authorities thought he was reformed when he behaved so nicely in jail, but no, he was the same sadistic rapist as before going to jail.

To think of this ugly and disgusting man with either of the two women he molested is difficult as it obviously is a "Beauty versus Beast"-situation. None of these women would have had anything to do with him on their own and now they were forced into submitting their life and/or health to him and his weird urges. It's both disgusting and crazy, but it made me think of a claim that we hear from many young men these years: "See me, sleep with me, be MINE!" Many of these men will be able to find a girlfriend or maybe a wife in the future, but some are so physically or mentally non-attractive that they will find such an exploit impossible. The point is, that that has been the fate for many women who ended up as "spinsters" which was considered "low class" for women.

This man, Lawrence Singleton, is not in any way lovable which means that he can't claim love of women who didn't chose him, but whom he still felt that he had the right to use for sex. In court over the Vincent-case he postulated that the young girl of 15 was a $10 hooker, and that someone else who, according to him, also was named "Larry" had been with her in his car, abusing and maiming her. He, on the other hand, "was totally innocent of all crimes". In court he was overheard threatening Mary, assuring her "that I will finish the job even if it takes the rest of my life!" 

Luckily enough that threat came to nothing. Mary lived to have a son, but all her life she fought to handle her handicap as best she could. From what I've read about her she is someone I would deem a "beautiful soul", whereas the thoroughly evil and selfish Lawrence Singleton is the opposite of her. 

However, asserting that doesn't solve the riddle of some men's feelings about their "right" to expect love from women who don't in the least feel attracted to them. When Mary asked him to "set her free" after being tied up and raped by him he changed from a rapist to a monster. Both her arms were chopped off when she said that and he tried to kill her, but didn't succeed. It makes me suspect that he was offended by her wish to get away and that that was the reason for his behaviour. Many other rapists and/or murderers, like e.g. Jeffrey Dahmer, behave in the same manner, and in my opinion that's very weird, especially as I suspect that it may be part of the male psyche as it has become ....
