You are welcome.
The example may sound bit farfetched but the intention was to show that you cannot get very specific in horary because it does not answer how so you will not have enough information whether to go on the drive or not. But if you were to not to go on the 10 hour drive, and instead if you meet with some minor accident on your way back home or any form of accident like almost hitting another car or something like that and sprain your back in shock or hot coffee getting spilled all over because you suddenly applied brakes, I would call these accidents that may happen in the next 10 hours. As you cannot the how part from horary it is up to you whether you want to call it fate or just coincidence or even meaningless.
Dictionary definitions could mean the same but fate is different from destiny. Fate is providence, the spiritual power which is the source of cosmos has a plan for all of us and we will not deviate from it. I strongly believe so.
Destiny on the other hand is how your actions mostly significant and consciously willed choices will contribute to what you would become at the end of your life. And fate is what drives you to your destiny and corrects the course at every step if you want to have tug of war with fate.
That is why I think fate can be seen in a natal's chart though it may sound silly not like everything clearly laid out but some hints about a person's destiny. Astrologers may have not purused thinking as no one can predict what actions an individual takes, so there is no way to predict someone's destiny.
Ethics should be definitely considered and it is up to an astrologer on how to tell something that may prove to be dangerous to a client. That is why astrologers are supposed to ask several questions not only to validate their findings but also to understand the mental state of a client. If some client constantly wants to have an appointment even for trivial things then if you are a smart and responsible astrologer you will not reveal dangerous things to such a person. I think it comes with experience I guess.
Ancient astrologers would not have told anyone you are a murderer or a wicked person, even if they did adding additional information that is not seen from the chart, the person would have had a choice, we all have a choice.
The example of Constantinople is a good one for electional astrology which is meant for things to last for a long time but not forever. Whatever may have been the reason didn't Constantinople play a key role in European history?

Now why wouldn't those who possess a specialized, priestly authoritative knowledge insist to others that they alone hold that knowledge? And that all should submit to them?
This is digressing from the topic but I think you already know the answer.
Probably the quality of astrologers is so bad or people do not care about the most opportune moment to get married by not believing in them but any good time is fine for getting married.
