The tree and village is an interesting setting for a melancholic, yet cute story and holds no deep religious meaning, nor is it trying to preach debauchery through some kind of twisted allegory.
You see it that way because that's what you know, because the bible has been drilled into your head since before you could talk. But your exercise in righteous condemnation is as meaningless as one attempting to ascribe deep religious metaphor to the angel wings on the girls in Haibane Renmei or why Enix chose to represent fallen party members in Dragon Quest as coffins following the player around with a cross on them.
