What would be unfair is a wild west approach to hunting where game was slaughtered for fun and left to die unappreciated. Or, an unsuccessful knife attack that wounded an animal and left if vulnerable to another predator shedding it after a run for its life. A rifle in lawful season is the most clean and painless way to harvest. A bow hunter usually isn't there to miss either and it is a challenging option for those who want that or for those who could use the food beyond what rifle season may afford.
