'might be' and 'are' is a pretty heavy distinction, kid.

the grimm do not learn fear, so much as they learn that their chances of accomplishing their goal are low if they charge in head first, so they wait, growing ever more powerful, and wait us to falter.

a squirrels instinct is to eat nuts, but they wil learn that eating them where they are found puts them in danger of losing it to another squirrel, so they instead store them and wait for a safer place to eat.

similarly, a grimms instinct is to destroy humanity, at first they will attack on sight, but as they survive encounters where their kin fall, they learn that simply attacking whenever they see a human is likely to end them before they can accomplish that goal, so they learn to wait, they wait for centuries until humanity falters, biding their time before enjoying their prize.
