You didn't add caveats to it or set conditions where breaking a promise might not be immoral. Since you created the stipluation there is no room for one to draw their own conclusions without going outside of the stipulations.
You are taking this far too literally. Consider:
Let us assume that breaking contracts is legally wrong. Hubert Husband contracts with Albert Assassin to kill his wife. Hubert, per the terms of the contract, pays Albert $50,000 down, with another $50,000 to be paid upon completion of the contract. Albert, however, has a change of heart and decides not to perform his part of the deal. Hubert then sues Albert for breach of contract. What is the result?
If you know anything of contract law, you know that Hubert will lose. That's because contracts to perform illegal acts are prohibited under the law: such contracts are void
ab initio, i.e. of no effect whatsoever. Yet we can still talk about the wrongfullness of breaking contracts
in general, even if it is not wrong for Albert to break this contract
in particular. In the same way, then, one can stipulate that breaking promises is morally wrong, but still hold that breaking
this promise is morally acceptable.
And if you're still having trouble reconciling those two principles, let me ask this: if Albert was wrong to break his promise to murder someone, was his action morally condemnable? Or, if Albert has another change of heart and kills the wife, should we then praise him for keeping his promise?
