mdd, first of all, execution and lashes were only done by the Beis Din of earlier times, who were on such a level that we can’t even imagine. Not by the rest of us. And definitely not in our times. And I’ve said what “diracheha darchei noam” means. It is a concept that tells us that G-d wants us to act in pleasant ways, in order to emulate Him. That means everything we do should be done in a pleasant way. And throwing rocks is NOT pleasant, no matter what the circumstances (excluding the execution of stoning which was determined by the Beis Din of earlier times, and is not applicable right now).
QB, I hope that’s a good thing!
