"It's tricky this time traveling business." Especially without travel insurance.
Dig, your scenario seems to have some strange consequences. Suppose Mr A in reality A travels back in time to save the victims, but saves the victims from reality B. Suppose that Mr C from reality C travels back in time to save the victims, but saves the victims from reality A. This means that Mr A never gets to save the victims from reality B. So without setting foot in reality B, Mr C is able to change the timeline of reality B.
