I always understood that the difference between pathetic fallacy and personification is that personification is a literary conceit, simply used for poetical or other effect, while pathetic fallcy refers to the practice of speaking or acting as if nature or whatever does actually have human traits.
When Tennyson said, "Tho' Nature, red in tooth and claw With ravine, shriek'd against his creed", he was using personification -- presumably he didn't think that there was a being called Nature which could shriek.
On the other hand, if you say in a discussion about the environment that you cannot accept such and such a view because nature is cruel, that would be an example of pathetic fallacy because nature is not a physical being able to take pleasure in making other beings suffer.
I must admit I fail to see how the quotations supplied fit in with this.
