It’s never justifiable, agreed, but I disagree that it cannot be understood or that the victimizer deserves special worse punishment or consideration. Before we tested for people on the spectrum, people that legitimately lacked the capacity of impulse control were executed like anyone else. Now courts bicker about how low functioning you have to be for such things.
Some people are born very low functioning and never get diagnosed, or throttle that line, and weren’t raised well, etc. Americans in general often refuse to see such nuance in such cases. They prefer to imagine a fair black and white world where every rapist is some evil mastermind when often they aren’t in control of themselves any of the time. It’s not like our mental healthcare system is robust enough to identify and mitigate those issues for poor kids who need it.
I’m sure there are regular and high functioning rapists, like Weinstein and statutory rapists, but I rarely see a differentiation between those calculated actors and some barely sapient person with sporatic impulse control who really doesn’t have the capacity to empathize with their victim or consider the consequences, but squeaked by on the mental competence review. Those are worlds apart imho and should be treated as such.
