Is it permissible to repent from borrowing with usury and to pay off debts from its usurious interests, and are the charitable deeds that are disbursed from this money invalid?

The questioner committed multiple sins, including borrowing with usury without compelling necessity, forgery, lying, paying bribes, guaranteeing his father's capital that he invested with, and then borrowing with usury a second time. He must repent sincerely by abandoning the sin, regretting it, and resolving not to return to it. The door to repentance is wide. He is not obligated to dispose of the wealth he gained from the usurious loan; repentance is sufficient for him.
