Like most creatures, a hawk would respond to it's environment. We see it in imprints all the time. However, there are things about them that are hard wired into them through evolution. No amount of medling on our part can change that. We might be able to skirt it to some degree through manipulation, but left alone they will revert back to what is natural to them.
Pigeons, domestic quail, some chickens, have been altered to a point to where they seem unable to survive on their own, and most probably wouldn't. But evolution leaves just enough seed to revert back if they are left alone. If you can imprint, or at least change the focus of a passage raptor from it's own species to humans, then a hawk that is imprinted on humans can be reverted back to it's own species. I think that nature would see to that. Maybe not in all cases, but in some. Even in wild hawks that is about the extent of it.
Humans are afflicted with so many different emotions that it makes it difficult for them to go through life without suffering due to it. If the majority of humans were placed into the wild under survival conditions, most would perish because they would be killed by their own emotions. The survivers would be the ones that are not bound by such things. I think that they might be called sociopaths. Most people's ethics are founded upon their emotions.
Hawks being solitary creatures for the most part, and focused on survival as it were, tend to be sociopaths. They feel none of the hold back emotions that we do. They do what is necessary to survive and they have no qualms about it either. The males feed their young by raiding songbird nests and stealing the young, and they sleep well at night. And like humans, the emotions that they do have are driven by hormonal change under certain stemuli. It is hard to change what nature has instilled over millions of years of evolution simply by hand raising a hawk.
