rarely have I ever got a second chance with a bow. Muzzle loader that's a different sound effect the animal just stands there. Rifle how do you miss? If the shot is right. You know the distance and have a rest.

Ethics hmmm that's a personal level of experience. Everyone that has hunted long enough will miss or wound. Shake it off and get back in the game. Most people that miss an animal don't calm down and make the next shot count. This separates the playing field.
