Answer:
I don't know the story, so I just went off of what you gave.
In my opinion, breaking promises is never good.
Explanation:
When you break a promise, you lose the trust of the person you made the promise to.
Trust is something that cannot be taken lightly. It can break easily, and it can take years to rebuild the trust.
Thus, I don't think Alexander should have even made that promise if he wasn't going to do his best to fulfill it.
It makes him seem untrustworthy.
