I hope the learning doesn't spread further, or gets more serious. Orca's are carnivores, and while they don't target humans, we are not so different from other mammals like seals, which they do eat. They have already sank muliple boats, it's not unforeseen for the life raft to get attacked, and for this to move from an unfortunate but interesting story to a very dark one, either for humans, or orcas.
