Has this ever been explained, especially in lieu of how in MKX, Sektor himself also played a role?
Let's look through it chronologically:
1. Sektor hires Quan Chi to wipe out the Shirai-Ryu, killing Hanzo, Kana and Jubei. QC creates the illusion that the LK did it.
2. Hanzo becomes Scorpion under the pretense that the LK (specifically Bi-Han) killed his clan and family.
3. The 9th tournament. Bi-Han is assigned to assasinate Shang Tsung.
4. Scorpion shows up and kills Bi-Han. QC turns Bi-Han into Noob Saibot
So to sum up, QC has wiped out the Shirai-Ryu, and claimed the highest-ranking fighters of both clans as his champions.
The question is, why?
