Well my theory is she wanted the last Lord Soul, but Light, Life & Seath's all had dreadful side effects. (creating the Iron King, Lost Sinner, and killing the Duke (but indirectly creating Freja)) Not wanting the side effects she gave the last soul to Pharros, who would then give her the power w/out side effects. He gave her a very small portion, enough to change her appearance, and fled the castle, consuming it for himself.

The more detailed theory is on the Rotten's page, and Bell Keepers page, where I link it.

Unfortunately I don't have the evidence really recorded down, yet.
