I have thought about this many times. Just say E&D hadn't killed themselves so early into the incident. What if they had barricaded themselves into the library ( i know that wasn't part of the plan ) Just say E&D decided they didn't want to die. The final time they returned to the library and walked around each desk and looked at all the dead bodies. Just say they became disgusted with themselves because they had murdered little girls , little girls who had begged for their lives ,little girls that WERE NOT A THREAT to them. Boys and girls that had parents ,brothers and sisters and friends. Barricaded in the library gave E&D time to think ,time to reflect and time to cool down. Once all that pent up rage and madness had diminished and returned them back into the innocent boys they once were. They both position themselves away from the windows and out of sight of the police snipers. They both cried and couldn't believe what they had become. At that moment ,they weren't child killers ,mass murderers and spree killers. They were kids ,just kids. A police negotiator arrives and E&D's parents too. The library phone rings and Eric picks up and can hear his mum screaming and waling and totally in hysterics. Eric has NEVER heard his mum in such a frenzied panic before. Of course not because he has never killed before. His mum has never spoken to this stranger on the phone before. Eric her child ,a mass murderer. We know that E claimed " I WISH I WAS A FU!*ING SOCIOPATH SO I DIDN'T HAVE ANY REMORSE ,BUT I DO. THIS IS GOING TO TEAR THEM APART. THEY WILL NEVER FORGET IT!.". If he heard his mum " torn apart " on the phone ,would that have made a difference at the end? Dylan on the B tapes just says a quick apology and goodbye. He doesn't appear to be half as sentimental and sorry as Eric. How would Dylan react upon receiving a phone call from his mum? How would Dylan feel if he picked up the library phone and heard his mums voice and it was almost like a foreign language? An unrecognizable voice of pain and void of understanding. A voice Dylan had never heard before ,the voice of a mother attempting to reach her murderous son. I think Dylan would have put the phone down and committed suicide. I am not sure about Eric.. What do you think about it?
