I couldn't save my younger sister, but I couldn't do anything different by then. For a different reason than you, and I was in a different position too, but the guilty of knowing if I have done something different she might be here...I guess it is a similar sense of guilty.

Carrying someone's death in the hearth is horrible. But I believe we never know what is happening next and we cannot know it, so we chose what it is the best with the information we have at the moment, we cannot be asked more.
