Inherent Evil

[Keneldil the Polka-dot]

The orcs, however, did not make a conscious choice to be corrupted. They had no say in whether or not they went against the designs of Iluvatar

That, I completely agree with. Evil is not passed on to them by their creator.

Since orcs are inherently against the design of Iluvatar (he did not want them to be, and it states in the Silmarillion that the corruption of the orcs was the "most hateful [deed] to Iluvatar"), then they are inherently evil.

That, I do not agree with. The choices Melkor made in creating orcs are what was evil. Their creation was evil, maybe even the stuff of their hroa was evil (I don't think so), but the orcs themselves were not evil. To say they were is to say their fea was evil. Fea, souls, are from Eru only, and are not evil. Even Melkor's fea was not evil. Choices made make evil.

Just because they are inherently inclined towards evil deeds, this does not mean they cannot be redeemed.

I'd say there is a huge difference between "inherently inclined towards evil deeds" and "inherently evil".

I wonder if we are having a semantics thing here.
