Psychiatric and criminological research has established a relationship between cruelty to animals and a host of other violent behaviors.
This research suggests that a single violent individual may lash out against multiple defenseless victims, and that any aggressive act—regardless of the identity of the victim—may be a predictor of future violent acts, as well as an indicator of current antisocial behavior. Ongoing research is exploring why people become aggressive and how that violence becomes a pattern of behavior.
Researchers are also investigating the negative consequences of children and adults witnessing acts of violence towards animals and humans, and how and why those witnesses are more likely to become violent themselves.
