I faced a tough predicament. There was no beekeeper in my area that would extract a bee hive that is in the attic ventilation holes without charging a hefty fee so I ended up allowing all the bees to enter the room that I made a hole to the attic from to die in. Beekeepers say they love bees, but everyone clearly has to do it for money. I am not sure there is much love in that. Now, I have a tainted soul with blood on my hands.
there is nothing wrong with killing honey bees. They are not native wildlife, they are livestfock. When you see a hive in your neighborhood, it's like having a feral goat living in your neighborhood - they are escaped livestock and don't belong there.
If they aren't causing a conflict, no harm no foul. If they are living in your attic, they have to go.
Just keep in mind that killing the bees is not enough. You have to get that hive, and the honey, out of your house. If you do not, you could end up with mold problems inside your home, you could end up with other pest problems in your home, or you could have another hive take up residence in the vacant hive. You could also get all three of those happen. You'll need to get rid of the hive either way. It's usually cheaper to have a bee keeper come out and do the work than to have a pest control company come in and kill it and remove it, then have a contractor repair the damage done in the extraction. That's primarily becuase the bee keeper is often hoping to earn money selling honey, and will often price that addional income into the price they quote you for the removal.
Just a pespective from a pro. I hope that helps you.
