Yes, the karmic stain from watching such content can be cleansed to a great extent through sincere repentance, pratikraman, stopping the fault, self-restraint, fasting, and pure conduct in Jain Dharma. But it is not “undone” as if it never happened; the karma already bound must be purified through right repentance and austerity.

Yes, in Digambar Jainism, a female layperson can go to heaven (devaloka) if the karmic causes are auspicious. However, no, in Digambar doctrine, a female body does not attain moksha in that same birth.

So the short answer is:

• Can the karma be cleared? Yes, through sincere purification.
• Can a female layperson go to heaven in Digambar Jainism? Yes.
• Can she attain moksha in that female body? No, according to Digambar Jainism.

If you want, I can also explain the Jain method of pratikraman and repentance for this specific fault in simple words.
