It depends on how you are looking at the timeline. We as humans dont have the capability to look at the timeline anytime beyond this second, so we do not know how it is meant to be. If we do not know how it is meant to be, we do not know if we are capable of changing it. Only a power capable of seeing the entire timeline has the power to know if things are to be changed.
Time travel is not possible, so this actually all becomes irrelevant. We as people do have an influence over our future, and thus, should try our best to change everything possible into our favor. Weather or not it winds up turning out good, or could have been better, we will not know.
