Most people who are pro life reason from their point of view. *They* would be hurt if someone innocent and with a life would die. Because *they* see potential there. *They* would not feel half as upset if a dangerous criminal would be put to death, which is a matter they have little influence in because the state does it anyway, vs what they view as an innocent who could be saved.
Humans self project. Us that want to die do the same. Because *we* feel what is in *our* minds.
It is probably the hardest for a bystander, to see anyone *they* feel has potential, talk about suicide. Thats why even here, many people try to talk the young ones out of it. When it comes to someone who looks like they do not have much options, that desire to save them is less. If you are terminal or to face a more painful death than suicide, people do get it more often. Because *they* can see it is hopeless, too. Then at the very best you get those who hope you turn to god, before you die.
