The man was an idiot with a god complex.
He got himself and his wife killed because he thought he understood Bears, when in fact, he did not.
They are wild animals, they always will be.
The way he acts at the start is like he's a child with a toy. Not a 2000lb Bear ffs!
This mans hubris and naivety got his family killed. There's no other way of putting it.
Irony is pretty clear too.
"Hey, I think I'll go and hang out with a pride of bigass lions. They're just misunderstood, but I understand them so they won't attack me"
*crunch, chomp, scratch*
No sympathy I'm afraid. He put himself and his wife in that danger, it was his fault, nobody else's.
