Do you kill random humans, just in case they have ebola?
Foxes, skunks, and raccoons are routinely killed because of their reputation as rabies vectors. While rabies is a problem, destroying healthy animals does absolutely nothing to control the spread of disease. It just causes unnecessary death and suffering.
You can prevent rabies by having your pets vaccinated, supporting vaccine initiatives for feral cats, supporting oral rabies vaccines for wild animals, and reporting any animal you see that has rabies-like symptoms (staggering, aggression, excessive drool, seizures, unusual vocalizing). Senseless killing isn’t the answer.
