Killer Whale Surprises People by Killing

I know the story is sad, but it isn't new. This same scenario has occurred before. Yesterday a Killer Whale, also known as an Orca, killed a trainer at SeaWorld. Normally these intelligent animals do not kill humans. That said, should we really be surprised that a captive orca that has killed twice before, would become annoyed with a tiny primate that is forcing it to do tricks? When the whale has the "unhappy looking," bent dorsal fin characteristic of captive whales, should we be so surprised that it (pun) "went off the deep end?" They are called, Killer Whales for a reason. They are the top predator in their realm. They are intelligent and have families. So why should we expect that one of these creatures should be happy living in a tank away from its family? Maybe it is time to free these whales, instead of exploiting them for entertainment income.
