In the nature vs nurture tug of war, I think we overestimate the extent to which parents' nature or behavior shapes who we are and I also think we overestimate the extent to which our parents' genes contribute - though both I believe to be highly significant. I see karma as factored into both and sprouting out alone as well the soul's daemon with no apparent earthly cause.
Disclaimers: I do not have court admissible evidence to back up my point of view but then again I don't depend on it - however things are is hidden from view it seems and whatever is is okay with me. The word soul to me is just a place holder.
