I don't disagree with you, but if they were dangling body parts into the tiger's exhibit it's hard to get too upset. It's like the case of someone killed in an accident with a BAC of .35. They didn't deserve it, but some behaviors tend to have catastrophic results. That's life.
How true:
“Stupidity cannot be cured with money, or through education, or by legislation. Stupidity is not a sin, the victim can’t help being stupid. But stupidity is the only universal capital crime; the sentence is death, there is no appeal and execution is carried out automatically and without pity.”
