Many pro-lifers oppose the death penalty because its modern uselessness and needlessness makes death penalty inhuman. However, in the countries in which death penalty has been abolished, it is very difficult to find pro-lifers supporting it. In any case, the capital punishment and the abortion issues are related only in part. There is a big difference between them. For universal agreement, the killing of the innocent is the most atrocious crime, not a civil right.
Nothing can justify the murder of the innocent.
Nothing can justify an abortion.
