What should be done about a maternal uncle who speaks about forbidden sexual matters and harms his sister's children by encouraging them to engage in practices contrary to the religion, and is it permissible for the mother to reconnect with him and welcome him into her home?

The man is advised to be informed of the gravity of his actions and the virtue of modesty, and the prohibition of disclosing marital secrets. The parents did well by preventing him from entering the house as long as he is in this state, and he should be shunned if he does not desist from evil deeds. The two brothers are advised not to listen to their uncle, and whoever among them watches pornographic films should be reminded of Allah and that he should be a good role model.
