Annihilation

Lena: Why did my husband volunteer for a suicide mission?

Dr Ventress: Is that what you think we're doing? Committing suicide?

Lena: You must have profiled him. You must have assessed him. He must have said something.

Dr Ventress: So you're asking me as a psychologist?

Lena: Yeah.

Dr Ventress: Then, as a psychologist, I think you're confusing suicide with self-destruction. Almost none of us commit suicide, and almost all of us self-destruct. In some way, in some part of our lives. We drink, or we smoke, we destabilize the good job... and a happy marriage. But these aren't decisions, they're... they're impulses. In fact, you're probably better equipped to explain this than I am.

Lena: What does that mean?

Dr Ventress: You're a biologist. Isn't the self-destruction coded into us? Programmed into each cell?
