So it's okay to perform the harmful act, knowing the harm it will cause, as long as you leave yourself the out of being able to say it'd have come to nothing had others declined to participate? I once heard a heroin dealer make a similar claim.
No, of course not; that would be foolish. I'm pointing out that this argument goes equally well to justify either practice, and a lot more ill besides. That makes it a weak argument, and it makes someone who uses it look likewise, because who'd go for this if they had anything better?
