Apa nak hairan? Darth Maul were split into 2 parts but still alive.

Because Qui Gon is like Spiderman's Uncle Ben.

He is the only one who died from lightsaber stabbings

Maybe he prefer to be force ghost.

he jelly reva tak mati

Not only Reva, the Grand Inquisitor also did not die.

Even Darth Maul cut into half not dead.

I just noticed, all who survives are using dark side of Force

Count Dooku deaded, really deaded.

maybe he not paying attention during Sith class.

That one not stabbed. That one kepala putus.

Pay attention also no use!
