I would need to go back to remember exactly, but were those Triune cultists or Lilith's cultists? Triune cultists originally worship the Three Prime Evils. Actually, the original form of the Triune cult worshipped the Primes without knowing they were evil.

I believe at some point Lilith co-opted the remaining Triune cultists into her order, they would probably still hold reverence to the original Primes in addition to her. I don't think the average cultist would have been aware of the rivalry between her and her father. If anything, they'd probably see her as being the Daughter of Hatred a kind of blessing.

Hopefully I cross-posted my own post correctly? I've talked more here in the past 2 weeks than several years of reddit!

Lord of Hatred

This is Mephisto

My perspective is that it's supposed to be part of the "who is the real enemy" angle that was a part of the later half of the game. There was this constant back and forth as to whether we should focus on Lilith vs Mephisto as the one to destroy. That process culminates in how the ending plays out.

This part is just a reminder to the player that Mephisto is still a force of evil that can't be ignored or underestimated.
