Don’t they know the great whites are an endangered species? I’m calling the environmentalists!

I recall a video from the Farallon Islands in Northern Californa of a group of Killer Whales killing a very large White Shark by ramming it in the gills and tearing it to pieces to remove and eat just the liver. Same exact thing happened in a video from Australia.
I wonder if they learned this in school.
Is this a positivin or a negativin?
I wonder if they eat the livers and wash it down with a nice Chianti.
Interesting thing, Orcas don't seem to be overly interested in attacking humans. I think they are smart enough to figure out that will bring results they don't want.

LINK: Penguin chased by a pack of Orcas saves itself from certain death
In this video, a penguin is being chased by a pack of Orcas. This spunky little guy manages to save himself by jumping into a boat (an inflatable boat!) full of tourists!
This Penguin became my hero. After he went under the boat and leaped into it from the opposite side to the astonishment of the watching humans, instead of cowering in fear on the bottom of the boat, he leaps up onto the slick side and parades in front of the disappointed orcas, who look at him sideways before swimming away in defeat!
Part of me suspects that is how the Mexican indigenous people (who were hunted and captured by the Aztecs for human sacrificial purposes) felt about Cortez. They may not have known much about them, but they knew a lot about the Aztecs, so Cortez became their new best friend, in the way these humans in the linked video became the new best friends of the penguin!
This was how I envisioned the Penguin:

Now, with no effort at all, the Orcas, who are CLEARLY not afraid of the humans in the boat, could have just tipped the raft and had their meal.
But they didn't. They sidled up to the boat, looked at the penguin who appeared to feel perfectly safe, and after eyeballing the humans, just swam away.
People may say I am anthropomorphizing those orcas, and I plead guilty, but I think they are intelligent enough to know that mangling or eating humans is not worth the problems it would bring down on them.
I believe they do a calculus, and decide to cut their losses and look for another meal. I really do think they are intelligent enough to understand that.
Interestingly, in the Shackleton Expedition, they saw huge blocks of ice that had been displaced by Orcas bursting through the sheet ice to get at seals and penguins on top, but...they simply looked at the humans with curiosity and showed no inclination to attack. Shackleton and his crew were quite wary of them and thought they would attack them the same they did the seals and penguins, but the Orcas never did.
They are really killer dolphins, not killer whales.
This is learned behavior. There are killer whale pods off the coast of Kommiefornia that teach the trick to their young. They’ve also been filmed around Antarctica teaching their calves how to hunt seals.
It’s like the humpback whales blowing bubble nets as a deception to cause their prey to form tight groups. It’s only been observed IIRC in three locations globally. One of them is in Puget sound, where only two pods know how to blow them. And they teach the trick to their young.
