The lion is treated more humanely than feedlot cows. Otherwise it is the same thing, farming. A rich person paying 50K for one and the other becoming 99 cent cheeseburgers doesn't affect the morality of humans farming cows and lions for our benefit.
I spoke about people not understanding what "sport" really is anymore. I like the analogy though. This is the same as getting a dozen cow heads staffed and put over your fireplace. Pretty lame ass "trophies".
