I would rather (and do) feed my bees syrup made from granulated white sugar than feed them honey from another apiary, no matter how reputable I felt the source... Pathogens like AFB are known to be transmitted via spores in honey and what may not adversely affect one colony that has been exposed to it for some time could have a devastating effect on another that has not had previous contact. If bees need emergency feeding then in my experience sugar syrup really is the safest option unless you have honey that you previously harvested from that hive. Think of it like giving someone a blood transfusion from an unmatched donor. It's all blood but some will make you better and some will kill you....better to give your bees the major components (ie sucrose and water) and let them turn it into what they need.
Bees are a little different to other creatures in that you cannot pen them in, so the difference between domestic and wild is much less distinct. In your continent there will of course be no truly wild honey bees because they are not native, but there are also no truly domesticated bees either because they come and go and swarm at will, usually despite our best efforts, and it is very difficult to control their breeding. The best we can do is provide a decent home and hope to take a little rent when they can afford it but also help them out in times of need, especially if they did not chose to live in the location we put them.
If I lose a swarm and it finds somewhere to live, like a hollow tree or house wall or roof, I agree that it lives or dies by it's own merit, but if I catch that swarm and put it into a hive of my choosing in a location that I have selected, then I have a responsibility to it because the choices I have made in those respects may not be as good as another location/cavity that they would have chosen for themselves and I do think that location is hugely important when keeping bees..... I currently have 9 colonies right outside my back door and even the tiniest colonies have survived winter, but I have previously tried other locations in my garden where the bees have been much less happy and not flourished. I don't know why 50 feet or so can make such a big difference between bees thriving and failing, but in my experience it can, so do be prepared to rethink your apiary site if you are having problems that you can't put your finger on..
