While the others were clearing the debris, they also collected the bodies of the people that were buried by those pile of debris.
Myla and the others moved fast; just after Nathan finished treating Liam and Zam, they managed to clear out all the debris, but in the end, they didn't manage to rescue anyone alive.
So, only the people that were around Treyton and the others were left alive, as they were included inside the metal walls that Treyton had made and were also protected by the abilities of the other members.
Treyton and the others were obviously affected because some of those that had died were the so-called slaves in the Sun Base, which means most of them were victims.
But in the end, they didn't react much and just covered those bodies and planned to cremate them all later on.
As for the rest of the subordinates of the dead leaders of the Sun Base, they were still tied up and would be dealt with by Treyton and the others later on.
