Bismihi ta'ala
Any sinful act can be forgiven by Allah ta'ala, as long as the tawbah is sincere, the act is abandoned, and it is between them and Allah ta'ala. This last condition means that there is no due right to be returned back to an individual.
What the individual did must repent, and work towards purifying themselves, and surely gain God's forgiveness in this world and the Hereafter.
And Allah knows best
