Falsified death certificates. Sure they may have had covid but the vast majority had even more deadly co-morbidities. Like the guy that jumped off a 20 story building and died of covid on the way down. Covid pays more than "natural causes".
Colossians 3:17 (New King James Version) "And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him."
