Agreed. I think it's a good thing, though I maintain my hope they don't just villain bat Turalyon.
To be fair, in this instance it is true that the Light isn't really subject to the same degree of moral convolution as normal, human characters. I think it was something of an odd retcon since the Light actually was meant to be a transcendent force which actually was devoid of evil. It seemed especially superfluous since the Light is a religion with multiple followers of multiple stripes, so it is possible for there to be a faction of extreme Light-worshippers who fail to actually execute its will as intended, such as we had with the Scarlet Crusade. We already had a pretty good excuse to have Light-themed baddies.
Honestly, I think the Titans were always better as cold, amoral Lawful Neutral aliens, which is how they were originally-depicted. This isn't a significant change... according to their portrayal up until Legion. The issue is that Legion and Chronicles kind of derailed this. The introduction of the Void Lords and the like gave Algalon and his ilk a very good reason to exist and made the origination process seem like an unfortunate but wholly necessary thing to save the universe. Unequivocally, planetary genocide is preferable to multiuniversal metaphysical annihilation or eternal torment by the Void Lords. In Legion and in Chronicles, the Titans were portrayed as emotional, fallible and humanlike beings that just happened to possess extraordinary power.
This change is a return to form, but does effectively turn Legion through Shadowlands into an awkward period during which the portrayal of the Titans was entirely different. It's a trough is a continuous line of character, and it makes things feel very inconsistent.

Honestly, that still needs a good explanation. Maybe Dragon Isles will open the path for a retcon that could help render that more sensible due to the amount of stupidity that it accidentally lends the Titans.
As for the Titans as a whole, my other comment on this matter sums it up. I like the reversal to the pre-Chronicle portrayal of the Titans as cold, alien authoritarian beings, but this also confuses things because they're also portrayed as fallible, emotional, and very much moral beings in Chronicles and Legion.
