Again, if capital punishment has any value as a deterrent, it should be effective here. Not only did she kill her rapist, but by shooting him in the offending member, then publicly disgraced him by dumping his severed head in front of the whole town and declaring him a rapist. It is like Jael and Sisera on steroids. So, yeah, sounds like we are on the same page here. Of course, if it turns out she made up the allegation it is an appalling atrocity, but it seems unlikely she would just decide to brutally murder a family member like that without provocation such as she stated.
