“Pro life” is a slogan
I am not “pro life” so much as I am against the murdering if innocents
I am not, however, against society deciding that adults convicted by a jury of their peers of heinous crimes should be put to death
This stance leverages the vernacular that has been adopted to address abortion.
If you put that aside - what you’re really asking is “can I simultaneously believe that it is morally wrong to murder the unborn while also believing that society should have the authority to put adults convicted by a jury of their peers of heinous crimes to death for the sake of continuing a civilized society”
The answer is obviously yes and that the two things are not contradictory at all.
