Arthur was in the past. There were moments when he needed to remind himself of that. However, the past was too cruel to see. The corpses began to line up the cave after Larza tortured them and separated those feelings from them before they died.
This was their method of harming the child without actually breaking it. Instead, they made it experience the suffering of others, and they kept stuffing feelings into it.
"This is true human nature," Shinva said with sadness. "They are hellbent on harming each other, even as a means to harm more. I sometimes feel that our existence here is a mistake, and we are all rejected by the world."
"Rejected," muttered Arthur quietly as he stared at Larza, who had a crazy look on her face as she separated a man's skin from the rest of his body.
"My Beloved," she chanted. "My Seika. We are going to be reunited soon. I will feel your power within me soon."
