This quote by Quintus Ennius talks to the concept that fear can cause hatred. Worry is an effective feeling that can trigger people to act in illogical ways. When individuals are afraid of something, they may lash out in an attempt to safeguard themselves. This can result in hatred of the important things they fear, as they may see it as a hazard to their safety or wellness. Worry can likewise result in bias and discrimination, as individuals might fear those who are various from them and might attempt to distance themselves from them. Worry can be an effective incentive, and it can cause hatred if it is not handled correctly. It is very important to acknowledge fear and address it in a constructive way, instead of enabling it to lead to hatred.
