Since always? If someone asks you a question you have a right to answer as you see fit, don't you? Shouldn't you? Even if you've entered into an agreement to keep a secret, it's only a legal contract that you'd be violating (which you have a perfect right to do) not a law.
You seem to be using “right” to mean something like the state of affairs where there is no criminal penalty. Am I mistaken? I don’t think most people understand the term in that way. So my answers would be no, you don’t have a right to answer as you see fit; no, you should not; and no, you don’t have a right to violate a contract.
Yes, I mean "right" as in action that may be taken with no criminal consequences. What do you mean by the term?
With this definition, you do in fact have a right to breach any contract as there are no criminal penalties for doing so. That's why most contracts specify what happens if they are breached under various conditions. There's a major distinction between civil and criminal law.
I mean something that it is wrong for you to do. You indeed do not have the “right” to violate a contract; that’s precisely why doing so exposes you to civil remedies.
