So I just discovered that I have been working next to the waste of oxygen that raped my best friend several years ago. I work in a manufacturing environment and I know that you can’t fire someone just for being a sex offender unless it directly interferes with work duties (in the US). But despite it being a primarily male workforce he does work with several women who have no idea what he is. He literally followed a woman home, broke into her house, and raped her. Him working here puts every female employee at risk. How is that not an unsafe working environment? How is it at even legal to employ him anywhere where he will have contact with women?
No. There’s a psychological barrier to killing, even in the mind of a criminal. That’s why most murders are actually people who knew each other and had enough emotion to overcome that barrier or people who were scared/abused enough that the barrier was no longer there. (It goes away as a defense mechanism)
