Explain how death conditioning works. Do you think it’s a good idea to condition children to not be afraid of death

From the text:

"Just returned," explained Dr. Gaffney, while Bernard, whispering, made an appointment with the Head Mistress for that very evening, "from the Slough Crematorium. Death conditioning begins at eighteen months. Every tot spends two mornings a week in a Hospital for the Dying. All the best toys are kept there, and they get chocolate cream on death days. They learn to take dying as a matter of course."

Death conditioning seems to prepare children for death, to desensitise them from any emotion or fear. Thus, dying simply isn't seen as a big deal.
