Moral does not always mean legal

Generally no

Depends on the law, I don't think killing someone is a good way of protesting the law against murder.

Breaking that law isn't going to make the government suddenly go: "oh no! What? Our law is making people go to jail? Oh I guess we'd better repeal it then!"
They made the law to get more income through fines or other means, they don't care if you go to jail

Yes, but be prepared to go to jail doing it.
