Palan, I advise you to read
Orcish Fear and
The Role of Fate in ME threads. Many problems you pose are (succesfully?) solved there
As for your remark, Bill. I'd rather say free will
is essential part and not mere faculty. You can force someone , or lure by lies, into doing something. Nevertheless, it does not mean aforesaid someone was not making moral choice on his/her behalf. "I'm killing him because someone else threatened to kill me if I don't" does not rob me of moral choice - free will. To clarify it a bit - free will for me is not "will to do whatever I will", but rather <font color="FF0013">"right to choose between what I'm given". And this kind of free will is always there for orks, if only they are of elven (or human at that)origin. Choosing (however forcibly they are driven to do it) to do evil, they are implying their own moral choice to produce their actions, and therefore are sinning.
