The thing to keep in mind is that these forces, whether it be Light, or Order from the Titans, or Shadow…characters in our world tend to ascribe good and evil motivations to these things, but really, those powers don’t care about morality. They are driven to do what their nature is. And so, the nature of the Titans is to impose Order on things. If you are on that program, helping them accomplish that goal, then they will be benevolent towards you, and they will help and guide you. Perhaps we’ll learn what will happen if you aren’t someone who agrees with their agendas.
The same could be said of the Light–what happens when Illidan didn’t go along with Xe’ra’s plan? Well, sparkles rained down from the sky […] Even, for example, in Visions of N’Zoth, when you think about the things N’Zoth was saying, he wasn’t like ‘serve my evil will!’ He was like ‘I can make you stronger! I can help you!’ There’s a bunch of bad stuff out there, you should be joining me and letting me help you do these things.’ You could say ‘was he lying to me?’ Well part of it…probably was. But there’s truth in it too.
These things exist beyond the morality we as mortals think of. As that more-cosmic storyline unfolds, those moral questions and mortal points of view, vs these cosmic ancient powers, will be something to explore.
Basically morality isn’t really a thing as far as the greater cosmos is concerned. It’s something that Mortals made up.
“But what about things like Revendreth and the Maw? The whole deal about redemption and the irredeemable?”
Much is said about sins in Revendreth, especially hubris. But they seem to avoid the word “evil”. My hypothesis is simple:
Being “sinful” is inconvenient or dangerous to the way the Shadowlands fulfills it’s purpose.
There is a hint towards that. Maldraxxus has evil people, but the Arbiter sent them there instead of Revendreth because those bad guys in particular had characteristics that could be used FOR the Shadowlands purpose, not against it.
So being bad clearly isn’t a problem as long as your badness can be useful.
And it’s easy to imagine why stuff like excessive hubris would be bad for the Shadowlands. If you’re head is too big for your skull you may simply refuse to fall in line, believing that your afterlife is beneath you and you are better than the actual God that rules the place.
Now imagine for a second the Arbiter receives the Soul of Gul’dan. To the Maw he goes, obviously. Why? Because Gul’dan sold his race to the Legion to destroy countless worlds for personal gain. His very existence threatens reality. And now his reality is the Shadowlands. So down to the Maw he goes, so that he can’t threaten the Shadowlands.
The concept of redeemability that the Shadowlands work with is not moral, but relative to the purpose.
