No, they convince themselves it isn’t rape. Rape is a lot less dark alley and a lot more sober person and person too drunk to say no or pressuring or some other means of soft power. Look at studies which showed that if you don’t say the word rape a lot of admit they’re willing to do it.

So what you get from executing rapists is someone who raped their partner either in an emotional frenzy or a coercive stage gets accused or has a flash of realization and promptly gets violent lest they die.

Also, as a woman I’m a lot less likely to accuse someone of rape they actually did to me if I know it could lead to them hanging in the public square. Suddenly the weight of their life feels like it’s on my hands and I don’t want them dead.
