Consider the cat.
Specifically, consider the cat’s drive to kill.
Ash’s monologue still fits, doesn’t it?
Ash: You still don’t understand what you’re dealing with, do you? Purr-fect organism. Its structural purr-fection is matched only by its hostility.
Lambert: You admire it.
Ash: I admire its purr-ity. A survivor… unclouded by conscience, remorse, or delusions of morality.
Don’t forget to feed your cat. It might just be waiting for that opportunity…
(h/t Alice for the inspiration)
UPDATE (09/14/2016): h/t to Jose for the purr-fect pun 😉
