As with Yuria, a hollow need not be mad. As a human losing the Dark within them is left a living decomposition, and Gwyn burned the Light within him and the same happened, the loss of deific status may require the removal of what makes a god powerful.

But even hollows do not lose the power they hold, with the Londor pale shade and Gwyn being notable. By the time he defected, TNK is mentioned to have inherited the power of lightning, and he clearly retains it despite his condition.
