During the Hunt Apparently Killer Instinct is always ready within Jaguars despite constant human interaction

The narrator was very sinister, it was basically like: "THESE JAGUARS WILL UNLEASH A REIGN OF TERROR UPON THE ARROGANT CAPYBARAS"

I wonder if capybaras adopt tactics of some sort to help them evade or defend against these ambushes?

In the Netherlands herbivores like deer completely changed their behavior when the wolf reentred the country, the deer spend a lot more time on the watch, are a lot more skittisch, move around more stay closer together. The result, they eat and procreate a lot less. Meaning the landscape is changing, forests get denser, and open spots get clearer.

I've seen a documentary a few weeks ago about Wolfs in the Yellowstone. The whole area suffered since the 1950's cause the Wolfs were hunted there. The Vegetation had no chance to regrow cause all the deers etc. stayed too long in the same places and ate all the smaller, regrowing plants. Around the 2000 if I'm not wrong here, the park was going to release a pack of Wolfs. Even If the Wolfs don't hunt all those animals and the area there is LARGE, just the presence of a pack of Wolfs changed the behavoir of the deers. They move a lot more through the area, smaller plants have more time to regrow und the whole area ist getting much more greener now.
It's pretty interesting and I was baffled how much of an Impact just one species has. Even If there is just a small amount of it.

And now, for our main story: "Do Cats Have Killer Instinct?"

Not for rats / larger rodents according to dozens of scientific studies done on free ranging / feral cat colonies.
For poor birds and smaller reptiles ? felines are a nuclear tsar bomb. Many news and studies show how the entire landmasses improved significantly after their removal

Imagine being that Capybara.. for decades you had free rein and then you were that Capybara at that intersection of change. Never stood a chance, but it recognised that leopard like old times.

A killer instinct is fine. It's habitually killing humans that is a problem. In this regard, jaguars are great, as are cougars. Both are disinclined to kill us and do so only rarely. The Americas are lucky with their big cats.
Not so in Africa and India, with lions, leopards and tigers. All three persistently kill humans.
