When does the soul enter the body?
You need to be careful when answering. I think if you say before fertilization then any unused egg potentially is an abortion. If you say at fertilization then you are saying that simple single celled organisms possess a soul and if you say after birth then if you abort the baby all you are aborting is just a fertilized egg and nothing else.
I honestly don't believe a soul exists but I am curious as to what people who do believe in souls think when they enter.
IMO it doesn't take a soul to make a life precious. I think a self awareness would be a quality that would determine if a life is considered precious and that would include non human life as well.
