One major ethical problem is that it objectifies a woman, especially a mother. In Indian culture, mothers are held in the highest regard. This kind of story also perpetuates a negative and offensive stereotype. It is wrong on so many levels, from violating the dignity of a person to going against cultural norms.
There are multiple ethical issues. Firstly, it's a form of slander against Indian mothers. Secondly, it promotes a culture of disrespect and vulgarity. It also can cause harm to the perception of Indian families and the values they uphold. Such stories should not be created or spread as they are against the principles of respect, decency, and cultural integrity.
The main ethical issue is the disrespect it shows to mothers in general. Mothers are symbols of love, care, and nurturing, and using them in a sexual context is highly immoral.
