Lorath and his really bad deals

I know it's an old talking point, but I remembered a matter that was previously discussed by a different user in regards to the "Lorath sells his soul for knowledge" plot point in Diablo IV. The claim was it was pointless, which is ultimately true. The common response to rationalize his decision was that he didn't know it until it was too late. However, on my way to a meraphorical fridge, I realized that when one really thinks about what happened previously in the story, his faustian bargain makes *even less* sense. Here's what the player, and presumably Lorath know by this point in the story:

• All the way until this point, the events of Rathma's Prophecy (or at the very least, how Rathma's prophecy was interpreted by the main characters at this point in the story) have been going exactly as written.
• Despite Lilith's plans of amassing a cult and subduing Andariel were foiled, her plans were staggering, and her plans were probably at the brink of realization.
• Lorath knew about the prophecy before the events of the game, and despite initially dismissing it, starts seeing the truth in it.
• Lorath knows that Lilith has Rathma's key, and Player gave him this information.
• Rathma's Prophecy explicitly mentions the Eastern Jewel. Jewel of The East is a common nickname for Caldeum. Leah knew it, Cain knew it, Lorath, having traveled a lot in his life, probably knows it. Having been the only place in the main part of the Eastern continent the main characters have not visited yet, the prophecy pretty much states "something big and important is going to happen in Caldeum at the end".
• The Gates of Hell are mentioned alongside Caldeum. There is a very clear relation between the two.
• The Player knows that Prava is gearing up to commit war crimes on Caldeum. She's pretty open about a "Holy War", and Kor Valar itself offers extremely hard-to-miss evidence that this is where they are heading.

Having all of this information, and being as skeptical and untrustworthy as the story paints him to be, "yeah, here's my soul for things I should have already known by now", should perhaps be the last thing Lorath would say in this situation, and yet he does. Am I missing something?
