Those guys were genuinely and universally damaged beyond repair in short order and as such didn't get much of a choice in the matter, but let's take someone else - Sons of Horus, or Death Guard - who is torn between following the order of his Primarch, whose loyalty is slowly disintegrating before his eyes, and the edict of his creator the Emperor of Man.
World Eaters have had "good guys"- Angron killed most of them on Istvaan III, but there's a character in Battle for the Abyss - and the characters in The Outcast Dead were jailed on the first news of the Heresy- before they could decide. They were stationed on Terra.

I think the third Garro audiobook is supposed to have a "loyalist" World Eater.

So there's room to have a World Eater in that role.
