You can see the difference between Christian martyrdom, and Islamic martyrdom. One is based on love and peace, the other is based on selfishness and violence.
What, exactly, did this death accomplish?
His death illustrates the difference between right and wrong, and that one's principals should never be compromised. It was basically a testament to faith.
That's the best way that I can explain it.
Unfortunately, that truth can never be validated, especially after the person is dead. Why die for something you believe is the truth, when the guy next to you can say, no, that's not the truth, and you can't prove it is....
I don't understand anyone's martyrdom.
The difference between right and wrong, are completely dependent on the individuals involved.
Do you really think God wants us to die, for a belief?
