How does the machine operator react to these situations?

From the text:

"The impersonal operator of the machine could, by wearing a special optical helmet, gaze into the soul of the person whom he was pumping out. What did the Eye see? He did not say. He saw but did not see what the Eye saw."

The other machine was operated by an equally impersonal fellow in non-stainable reddish-brown overalls. This machine pumped all of the blood from the body and replaced it with fresh blood and serum. "Got to clean 'em out both ways," said the operator, standing over the silent woman. "No use getting the stomach if you don't clean the blood. Leave that stuff in the blood and the blood hits the brain like a mallet, bang, a couple of thousand times and the brain just gives up, just quits."
