They're not put on earth to be martyrs; they have to want to come out. It depends on your culture, where you work, where you live. Each person's circumstances are unique.
I have been astonished that men could die martyrs for religion - I have shuddered at it. I shudder no more - I could be martyred for my religion - Love is my religion - I could die for that.
I nursed men back to sanity who were driven to despair. I solicited clothes for the ragged children, for the desperate mothers. I laid out the dead, the martyrs of the strike.
While I do not suggest that humanity will ever be able to dispense with its martyrs, I cannot avoid the suspicion that with a little more thought and a little less belief their number may be substantially reduced.
