Because his arrogance and total disregard for human life resulted in the death of SEVEN people, including parents and their young children, and I think one mother who was pregnant when she was killed.  Because of what Pflueger did, many including myself have ZERO sympathy upon learning of his death.  Also like Trump,  I dont think he has ever sincerely admitted what he did was wrong that caused the deaths of 7 in the Kaloko dam disaster except possibly having to read a statment written by his attorney for some court requirement.
