Put yourself in the fish's shoes. If you had a choice, would you rather go out quickly and painlessly or die a slow death in the freezer because someone "wasn't comfortable with killing?"
I personally don't do it, but I thought the freezer method was used because the lower temperatures put the fish to sleep and then would keep them in their sleep.
