This is one of the arguments I've seen that doesn't sit well with me. How is this different from saying that it's ethical to steal money from a convenience store, because I'm willing to go to prison for it? After all, jail time is the pre-negotiated outcome for thieves, and I might decide I'd rather have the money and do the jail time rather than refraining from stealing in the first place.
Apart from one being in the criminal realm and the other in the civil, what's the difference? Or is that the difference that justifies the one and not the other? (Why?)
