Gargoyles are almost universally evil because they lack a functional society with caring communities. You never see baby gargoyles being led by their parents to an outing at the park or the zoo. No, gargoyles are abandoned at their creation to figure out the big, bad world for themselves.
Quite often a young gargoyle will try to introduce itself to new creatures it meets, but its attempts at handshakes and hugs injure most creatures who are not made of rock. They panic and attack the rock-based gargoyle out of fear. It quickly learns that the best option for survival is to hide in plain sight by being very still and then take what it needs from the squishy creatures.
