[The Might]

Well, I think we pretty much got a conclusion, or at least I have mine.

Orcs as a society are incapable of living together in peace, although there do indeed seem to be certain exceptions from this rule.
However, I am wondering if these exceptions were only moments of kindness or hints that there is more behind it.

If that was the case could it be that these Orcs were not understood by anyone, including the Valar? Because we see there would have been some hope for Gollum, but never anything is said of Orcs.

Probably only Eru knew if any of them were redeemable.
