One thing that's never really been explained is why Scorpion's family and clan have never returned from the dead (before the elder gods in MKA brought back Scorpion's clan as hellspawn, of course) themselves.
Is it because Scorpion owes his resurrection strictly to Quan Chi? Can dead people in the MK universe be brought back to life only if someone else decides to, or helps it happen? Onaga, despite still existing beyond his death, had no body, and had to orchestrate events that would eventually get him a new one. My point being, that nearly, if not all resurrections in the series, always seem to require someone else to help bring back the deceased to life.
Getting back to Scorpion's family and clan, seeing as people go somewhere after they die, they probably are in hell right now. Did Scorpion not bother searching the netherrealm for their souls? Could Quan Chi have made sure that they wouldn't risk telling Scorpion the truth, by, perhaps, wiping them out entirely?
