The alternate view, expressed in the BSG threads but rarely (ime) in alignment discussions, is that some actions, regardless of their target, indicate a depraved nature on the part of the actor.
I think there's a lot of truth in that, but I don't think it's the whole story. I think, to a large extent, it comes down to enjoyment (or sometimes expedience). If the actor is performing these acts because he enjoys doing so, then that clearly indicates to me a depraved nature. Likewise, if other options are available, but the pain/suffering/torture route is chosen because it's quicker or easier than the alternatives, then that's a very dangerous step.
However...
That is, even if orcs are intrinsicly evil and every orc baby will grow up to be the enemy of humanity, a good person should not be able to chase down a screaming toddler and spit them through the back without needing some major therapy afterwards.
If Orcs are truly, inherently Evil, and have no choice in the matter, then exterminating them is little different to wiping out a plague. Which is not to say it's something that one should take any pleasure in, or draw out beyond the cleanest methods possible.
Additionally, the moment you find even
one non-Evil Orc it puts the lie to the whole "truly, inherently Evil" line of thinking, and extermination becomes unacceptable.
Even if the cultist is completely depraved and literally soulless, a good person should be unwilling to inflict pain until they give in.
Unwilling, certainly. And, indeed, I would argue that the torture suggested would be Evil in all cases. I will certainly accept that sometimes such actions are necessary. But I don't accept the argument that the necessity of an action makes it any less Evil.
