(beginning note: it is no attack on You, and every "You" just keeping convention - no offense intended.)
Now, we talk about philosophy.
Why is killing for your family better than killing for yourself?
What makes so called "fighting for tradition" something ok? Especially, when "tradition" is usually just collective convenience?
Even if you call it "altruistic reasons", it is actually about You.
Those are Your loved ones. Your traditions. Your tribes honor.
So actually, it is just indirect way of fighting for yourself.
End of philosophy.
Start of personal note:
In my opinion, there is no "just war" - war is by default almost ultimate sin, no matter what excuses you have.
And Sinan wages war against whole world around him. For this, he deserves heavy condemnation from Reaper, and death from people, but he deserves death as a "Enemy", just like those, who bomb cities, or use deadly gases.
His death is necessary, for safety of everyone around him, but that's all. Calling him bigger sinner, than those who can find more comfortable excuses for their actions would be hypocrisy.
End of message, i hope, that i didn't cause too much anger. Those are only my opinions and you can disregard them freely. May there be peace between us.
