I know this article is not too recent but it is very interesting. This woman got 5 to 15 years in prison. Is this reasonable considering the psychological problem that followed this action? After years of sexual abuse by her own father she came to a breaking point and decided to unintentionally kill her father by castrating him to protect her nieces. I do agree that she does deserve the years given in prison. However, she needs to be evaluated and treated very intensively. Her behavior and actions that took place only individuals with extreme psychological problems will do. I still believe that what she did was not the way to go. What her father did was more than wrong, it was sickening what she could have taken other measures such as turning him in to the police or escaping from his presence. However, like mentioned before she has psychological problems and she decided to resolve the problem the quickest way and castrated him and boiled his penis. What somewhat surprised me was that she actually planned this ahead of time by doing some of her own research on the possibilities of reattaching the penis. She did not think about her actions and the consequences that she might have to pay stop. Not only that but the judge did not take this into consideration that this was a premeditated crime.
