What does this have to do with anything? It doesn't make sense to arbitrarily assign responsibility to some agent down the chain of causation on the basis of some positive, yet entirely unrelated, consequences of a later date.

Still, that Lalaith was always accidentally stepping on bugs on the step of her house so from their point of view - thanks Maedhros!
