Ok, so what if Lowell is not a single person, but as the old man said (let's call him Big Bro, if you get the reference), that descent is transferable.
They just need a person who is brainwashed into believing that they are Lowell and then transfers the descent to them; in this way, 'Lowell' will never die.
And maybe this whole Orwellian situation is created to achieve two things:
- Radio broadcast of Lowell's voice everywhere.
- Stressful situation for everyone.
This whole thing is just a massive program to create lots of humans with descent. They don't care if Lowell dies; he is replaceable.
And as we know, Descent is transferable, so in the end, they will capture everyone with Descent and use it to create some kind of superhuman army.
Then the real true villain is the Big Bro and the people working with him.
