From Catholic News Agency:
One recent survey shows a majority of U.S. Catholics supporting use of the death penalty for murder convicts. The poll numbers follow a 2018 update to the Catechism that the death penalty is “inadmissible.”
According to a survey of 5,109 U.S. adults by the Pew Research Center, conducted from April 5 to 11, 2021 and published in June, a majority of U.S. Catholics either “strongly” or “somewhat” support use of the death penalty for murder convicts. Mirroring the responses of U.S. adults overall, 31% of Catholics “somewhat” favor the death penalty for those convicted of murder, while 27% of Catholics “strongly” favor it.
