She collects souls of the recently departed. Presumably she could kill to get them, but it's implied that the Soul Collectors go out looking for them to bring them to her.
There's no evidence that either Kikyo or her Soul Collector harm anyone to get he souls.
The souls collected are at least delayed from making it to their final resting place. Kikyo herself expresses regret for this, but her constant need for souls implies that she can only draw energy from a soul for a limited time. What happens to the soul after that is unknown. I would like to believe that the souls are not consumed or destroyed, but instead held for a while to sustain Kikyo and then released.
