It is completely unethical. Nuns are dedicated to religious life and celibacy. Having sexual relations with them goes against the very principles of their religious commitment and the respect due to their vocation.
Sharing such stories is completely inappropriate. It involves violating the privacy and dignity of others as well as going against moral and ethical norms. We should respect all religious figures and promote positive and respectful communication.
Well, it's a very serious matter in a religious context. The religious institution would likely view it as a desecration of their sacred values. For the nun, she may lose her standing in the religious community. And the person who has sex with her might be condemned by the religious authorities. There could also be a negative impact on the reputation of the whole religious group. It goes against the vows of chastity that nuns take and the moral code of the religion.
In The Nun 2, the plot likely builds on the previous installment. There could be deeper exploration of the nun's background and her sinister influence on the characters. Maybe new locations and characters are introduced to heighten the tension and horror.
The story of the nun often involves elements of mystery, spirituality, and sometimes horror. It might center around a nun's experiences, challenges, or supernatural encounters.
