There is a qualitative difference between this sense of injustice and what the Creature
has felt earlier. Here, after doing a good deed, he has been been judged undesirable
in a preemptive manner and physically punished. Thus, what festers mentally as well
as physically is that a simple action to save a life has been met with a violent,
life-threatening reaction from the larger society of human beings. He feels no longer
merely rejected by this world but actively menaced.
