Do you know who the wildest killer in the wild is?
Crocodiles are simply "programmed" to kill. It's genetic, all they do in their lives is eat other animals.
But do you want to know who the wildest killer in the wild is?
It's the hippopotamus
Hippopotamuses are herbivores, yet they will kill almost anything stupid enough to come near them.
These crazy savages have one of the strongest bite forces at 1800 psi and can run at impossible speeds, up to 50 km/h despite weighing an average of 1750 to 4960 kg (1.5 to 5 tons).
When he's not trampling on his victims, he literally cuts them in half using the enormous hydraulic pressure of his mouth.
And he may do all this just for fun. He won't eat his victims because he's a herbivore
