There is no law against murder, only a law that requires the punishment of murderers. ("A person who commits X, Y, or Z shall be sentenced to W.") There is, however, a moral imperative against murder ("Thou shalt not murder"), as well as a moral right for me to protect myself from harm. The validity of moral imperatives and rights does not depend on the existence of any law. I definitely care when people disobey moral imperatives or violate moral rights.
As a matter of fact, the majority of people in any society obey the majority of the law the majority of the time. After all, laws are often specifically designed to coincide with what the majority thinks is right, convenient, reasonable, etc., so the majority will obey those laws for the sake of doing the right thing, doing what is convenient, doing what is reasonable, etc. But if you want people to obey the law for the sake of obeying the law, I don't see what might justify such a demand.
In my opinion, criminal law is just a device to facilitate obedience to moral imperatives. (Other laws might serve other purposes, such as facilitating commerce.) It's like a proxy server that helps me talk to an authoritative data source. A lot of the time, the proxy is good enough. But if the proxy interferes with my websocket, I have every right to bypass the proxy and talk directly to the data source. Note that this doesn't mean that I'm going to ditch the proxy altogether. I'm still going to use the proxy for all of my non-websocket needs because it's faster, better documented, etc.
By the way, sorry for the vagueness surrounding the phrase "has the right". I meant it in a justificatory sense. In other words, if and only if a law contradicts moral imperatives, anyone has JUSTIFICATION to break that particular law and try to evade punishment. If, on the other hand, the law coincides with moral imperatives, there can be NO justification for breaking it (not because of the law but because of moral imperatives), but a person may still be justified in trying to evade punishment depending on whether the punishment is moral. For example, if the law requires disproportionately severe punishment for a petty crime, that's immoral.
