There are species that have negligiable sensesence, QED death isn't vital part of evolution.

But even if it was, why should we limit ourselves to evolution? Evolution did not design us to go to the moon, to split the atom, to have transplantable organs, to fly, to brush our teeth with fluorinated toothpaste, or to use contraceptives — it has only just managed to keep up with us wearing clothes and cooking our meals.
