Thrill of the kill

How is it considered normal or healthy to enjoy killing anything?  i.e., hunting for sport. I can understand someone hunting out of necessity.  This was probably far more common in the past, at least in the United States. Someone lived out in the deep woods and had to grow, hunt down or prepare their food. If you failed to gather or kill enough, you simply went hungry or even died of hunger. Or worse yet, you watched your family die of hunger. But that really is not the case any longer. No one "needs" to hunt in order to survive.  
And it cannot be argued that hunting is less expensive than buying groceries. I suppose that someone could argue that literal "wildlife" hunting/poaching is less expensive, if one is not picky about what one eats. But typically, the hunting that takes place is the "take one week of work off, pack up all the hunting/camping/hiking gear, buy a hunting license and ammunition" type of hunting. Which is not an inexpensive endeavor.
But to enjoy killing? Simply for the thrill of the kill? "Hey, look at that beautiful animal!  Let's kill it and hang its head on our wall."  Personally, that sort of mentality seems antithetical to the Christian faith. Man didn't eat meat until after the Great Flood. The animal sacrifice that took place in Old Testament, during the Old Covenant, was a direct result of and temporary covering for, sin.
I don't understand the enjoyment of taking the life of something else.
