“Torturing and or killing pet animals is an early indicator of an expression of inner hostility. Such an individual, as they grow older, will then extend that very same hostility towards not just animals, but to people around them.”

“It indicates that as an adult, he’s gonna get pleasure out of hurting people, and that basically gives him a sense of power, out of deliberately causing them pain, and making them suffer.”
