>1: Does the soul get bestowed at conception or at a later date.
Conception.
>2: How is the soul bestowed on the foetus? What I mean is does God himself personally bestow a certain soul to a certain body and if so does that mean God damns people?
It's not important "how" it happens.
God doesn't need to damn anyone. We do it ourselves.
>He that believeth in him is not judged. But he that doth not believe, is already judged: because he believeth not in the name of the only begotten Son of God. (Jn 3:18)
>Like does God bestow personally a soul to Iran and hence decrease the likelihood of that soul becoming Christian?
I think you are throwing up an disingenuous "gotcha" here. Do you honestly think that most people in Christian countries find Him in their lives? If so, do you think they are able to persevere until the end?
Everyone has the potential to find Him in life, but few do. Some people have the privilege of being born to Christian families, or even in Christian nations, but many again fall away through apathy or hatred. Since there are no actual Christian nations anymore someone born in Berlin or London of Madrid has odds-on the same chance of salvation as someone born in Tehran or Outer Mongola. In fact the lattermost has prbably the best chance since his presumed lack of access or total (and thus invincible) ignorance would stand him in better stead than someone who is raised in a "Christian" country but totally rejects the Faith.
