Isn’t a knife also well suited to this purpose? Assuming the animal is on the ground and not able to move well. Though I guess it depends how injured they are

No. An animal is unpredictable and can still kick.

One could argue that the fact that the animal which you are trying to kill has a chance of hurting you back makes that the only sporting option.
