"Should every human being be forced to kill another living, multicellular organism that is highly similar to humans and watch it die before your eyes." No, certainly it's a hobby that some people enjoy, but I don't go around saying, "Oh, everybody should make art in photoshop at least once." And really, the implications of learning PS is far, far less than learning to shoot a gun/bow and then kill another living creature.
Hunting is a sport for some and a living for others. However, it is not exactly a "must" for everyone. There is not reason why everybody should go hunting at least once.
Some people find hunting an enjoyable activity but some do not. There is no reason to simply require or advise everybody to go hunting at least once.
