Bobby Sands was not a hero. He was an unfortunate romantic, involved with an organisation responsible for over 2800 deaths in the name of "nationalism". He was probably not a bad man though.
As Margaret Thatcher said "He chose to take his own life, a choice not given to many of his organisations victims." (Or something similar).
There was nothing good about "the troubles", nothing that justified so many deaths and so much tragedy. There were no "gallant paramilitaries fighting the imperialist Brits" there was just death, pain and suffering - and for nothing, ultimately.
