Автор, что характерно, такому отношению читателей тоже удивлялся.

One has noticed that readers, as they wade on through the salt waters of the Saga, are inclined more and more to pity Soames, and to think that in doing so they are in revolt against the mood of his creator. Far from it! He, too, pities Soames, the tragedy of whose life is the very simple, uncontrollable tragedy of being unlovable, without quite a thick enough skin to be thoroughly unconscious of the fact. Not even Fleur loves Soames as he feels he ought to be loved. But in pitying Soames, readers incline, perhaps, to animus against Irene: After all, they think, he wasn’t a bad fellow, it wasn’t his fault; she ought to have forgiven him, and so on!
