If we time-travelled and changed things, would the outcome be worse?

Depends on what you changed... i mean, it probably would be worse, but there are slim chances that things would change for the better... i probably have too much spare time on my hands tho... 😛

I'm one to feel that things happen as they should.. but if we were to change things for the better.. we would have to be able to determine a very specific branch of actions that would give the affect for a desired outcome, especially if that change required to manipulate the course of action of more than one individual.
