If you were the Christian God, and Jesus were your flesh and blood, would you...
Would you put your own flesh and blood through the suffering and agony that Jesus went through both socially in his community and physically on the cross?
A fetus is like a glass in a box. Once you open the box, and take the glass out, you get your grubby finger prints all over the brand new glass.
You can't have kids and avoid getting your finger prints all over them. Some kids are more resistant to finger prints than others but in the end, they all end up smudged.
At some point in your life, your kid will feel hurt by your words and actions. Only people who do not have children think differently ;)
