How do you evaluate a life?

Placing importance on quality of life need not lead to denying the equality of lives. To say that all life is of equal value is to say that every life should be treated with the same respect and that no one has the right to judge one life to be more inherently valuable than another. This does not mean, however, that we cannot take into account quality of life when deciding how tightly we should cling to it.
