I saw this story earlier this week. I've actually seen the video of the chap walking into the lion enclosure.
Thing is - just because you've raised a lion from a cub, doesn't mean that the lion has the cognitive reasoning to think, "Oh, that grey-haired bloke over there, he's a mate of mine...not dinner."
No, the whole thing about wild animals is that they're wild animals. A lion is a lion is a lion. If you walk into its enclosure, technically, you're 'upright hors d'oeuvres'.
The lion should NOT have been killed.
