I can't even imagine what you are up to haha. No, I don't think the ends justify the means!
That's just like asking is it okay yo sell street drugs for a charity?
it depends if there are mitigating circumstances
Sure, it's okay to do something bad in a good way, isn't it?
Even when I say no to my son for money I always remember tough love doesn't mean I have to deliver it in an unloving manner. So no unless I am telling someone abusive to back off, although that doesn't happen to me anymore , not these days.
