Not the descendants that accepted and kept their family’s blood money without a second thought. The moment you, as an autonomous adult, choose to accept the power and wealth reaped through human misery, you accept the legacy of blood that came with it.
Anyone can walk away from blood money, or use ALL that blood money solely to provide restitution to the populations exploitated to obtain it. It doesn’t happen though, because human beings as a rule are the fucking worst. Most people, the fuckees, fantasize about becoming the oligarch fuckers, instead of dreaming of ending their oppression and restructuring society to prohibit amoral levels of wealth/power accumulation. Most humans, given power/wealth, would use their own suffering as an excuse to propagate more suffering.
