I let him walk/hop. The rabbits here (CO) have fleas that carry the Bubonic plague. We had one human case of the plague last year. If I see a skunk or raccoon during the day, I shoot, as they are almost surely rabid. I actually would have never thought of hunting skunks until I talked to one of my neighbors after seeing a trap in his yard. When I asked him what he did with them when he trapped them, he said he covers the trap in a black tarp and puts it in the 100+ degree sun and lets it die. I know that hunting them would be much more humane than letting them be killed that way.
