Sure, that is more or less what I meant by expressing an aversion to molecular biology: I have some living to do, so I can't invest effort in avoiding death. It is however true that there's a tiresome trope in fiction, the villain whose badness is centered on the search for eternal life. I remember more than one Doctor Who baddie with this quest. It's like a signifier of an evil character, like desiring unusually long life is a sin against destiny, or somehow unfair, and this trope gives life extension a bad rep. This probably stems from witch hunts in the 1500s, and fairy tales.
