Why were Wendy and Peter so apathetic about the death of their parents at the end ?
I think that the kids are more concerned with their own technologically driven world. In this condition, human connection is secondary. At the same time, Peter and Wendy have assumed so much power because of technology they are at the point where they see their parents as potential threats. Peter and Wendy clearly understand that their parents are seeking to remove the room from them. In both of their minds, they cannot let this happen. When the parents become victims to the room, it is evident that a threat has been neutralized and in this, there is little remorse or feelings, in general, felt about the death of the parents. I think that the parents have found themselves victims to both technology and the benevolence of modern parenting. Bradbury constructs the narrative so that the parents clearly become victimized by their desire to "give" their children all of the best. In doing so, the children lose respect for their parents, becoming more attached to things than sentimentality. In the process, the lack of affect becomes evident in how the children view their parents and the apathy that results upon their deaths.
