What was the last test at 134th floor?

As we all know the last test is what created the split between Jahaad and the 10 families vs V and Arlen. And I started thinking what could have happened there to create a rift between former friends who were so close to each other.

There are theories going around that when they would have reached the stop, the tower would have ceased to exist and the adventure would be over or his story would be over after this or there are other axis beings outside the tower, etc and I am not going to lie they are all plausible theories.

But I have thought of a new theory.

What if the last test was something like a battle royale to death between all of the people who have reached that last floor to select the strongest among them?

Why am I thinking about this?

Remember the flashback of Tramaurie where they had to let a lot of people die and Tramaurei pulled the lever or something to do it.

There was a statement that came up there particularly saying "The tower makes them cruel".

That would be a very plausible reason why Jahaad and 10 of them decided not to climb further while "V" and Arlen decided to go with it.

The only part that is very out of character here is "V" and Arlen wanting to go further despite the test because why would they want to get their friends killed but we don't know everything about them, especially after seeing V's actions in the recent chapters.

What do you guys think?
