A person who helps to secure abortion is in the eyes of God ex-communicaed from His Church.
Formal ex-communication only works when a person is able to fear eternal damnation, which hasn't happened for at least 500 years - it was designed to help the person to see the error of their ways and seek repentance.
If Governor Cujo did fear God and eternal damnation he would never have placed his hat into the pro-death camp. His punishment will be even greater due to the responsibility associated with his act.
It also works to make clear to the faithful that the person's public behavior is gravely sinful and should not be imitated or emulated.
