The true reason the Tree Spirits acted this way was due to their innate shyness and their fear of being hurt.
Because Tree Spirits are an immortal fae race, as long as their symbiotic trees do not die, they will not perish. Even when their symbiotic trees are on the brink of death, they can avoid such a fate by transferring their symbiotic spell.
However, once they fall in love with someone, it marks the beginning of tragedy. For their lovers are destined to die before them, and their deep devotion to love makes them unable to escape this shadow. They spiral into madness and withering—not death, but a dreadful darkness, living off destruction and reveling in tearing apart loving couples.
Thus, the simplest and most brutal method is to end things before attachment arises and shift all emotions towards a newborn, which becomes the most perfect choice.
