Does the deceased's obligation become cleared by returning money he took unjustly while alive?

Returning rights to their owners cancels the claim for them in this world and the hereafter. However, the sin remains, because the conditions for repentance related to the rights of people are four: remorse, cessation (of the sin), firm resolve not to return to it, and returning the rights. So, if the rights are returned only without the other conditions, the claim for the right is dropped, but the sin remains, and its perpetrator is subject to the will of Allah.
