Self-Centredness

Something has attacked the city and was killing off the inhabitants...like an epidemic or genocide. I was busy escaping off when 'movie' of the dream is re-winded back to the point were I am in multiplex just before the cataclysm. I see a sweet looking toddler at the ticket counter and the train of thoughts go this way:

Why don't I save the kid from the impending horrible death?
But if it is impending, what can I do about it? You cant save everyone in this world?
You are wasting precious time...SAVE the kid!
Why should I change anybody's destiny even if this was possible?
