The second elder was tortured to death.
After creating enough spatial tears, Sam didn't bother to attack him any further and he died as his body was being sucked by the different spatial tears.
His death was gruesome and all the while he was dying, he yelled different things.
"I need to be more powerful."
"I am weak."
"I am Pathetic."
"I want to be strong."
He yelled these things like a crazy maniac. Sam's trick really did work wonders. No matter how torturous death is, the dying man would always have a moment of peace before death. As his body and mind would accept that it was death, they would just let it go in the final moment.
But the second elder didn't have that chance as Sam used that trick on him. He wouldn't find peace even in death.
Even the tribe head who wanted to kill the second elder desperately a few minutes felt a sense of pity for him at that moment.
