Many find the martyrs inspirational. And many believe that what they died for to be truths. For what being would die for a lie?
Well, no one dies for a lie. But do realize that many lies are dressed as truths. And many men cannot undress them even if their lives depended on it (which ironically, it does).
A thing is not necessarily true because a man dies for it.
Oscar Fingal O’Flahertie Wills Wilde
