The hard part of hunting is to know where to set the snare or how to come close enough for a shot (I shot roe deer at less than 30 m but it isnīt easy to come that close). Even if you decide that you canīt kill an animal, it may be worth aquiring the other skills. You will learn to observe your environment which can spare you a lot of trouble.
Apart from hunting you could learn how to prepare game or fish for eating. As others said, having one more skill canīt hurt.
