i dont think it was the toilet paper incident that really was the reason behind the killing
ill explain
my history teacher gave a very good example
suppose you hold a grudge or you dont like someone
and suppose you keep silent about it and just keep hating him more and more inside
one day he is simply tapping on something and you snap "STOP THE TAPPING IM TRYING TO CONCENTRATE YOU IDIOT!!"
now think, is it really the little tap that he is doing that caused the other guy to snap? or did the tapping trigger the release of all his anger that had built over the years?
i think in this case it was probably some other issue but the toilet paper incident triggered the final step to breaking out in anger thus causing the death of an innocent human
