If we live long enough. Of course, this is an assumption. It is neither a guess nor a basis. It is just an assumption. The time dimension can be extended long enough. Looking at the present from the future, we are also unwilling to abandon the interests of others and simply grab the interests. To be more direct, we abandon the individual to achieve the collective. Another example is that we cannot let go of what we have and look down to re-understand ourselves. Of course, there is another situation, which is to fulfill ourselves. It belongs to the category of sacrifice. Our own decision has nothing to do with others.
