My pet. In a heartbeat.
It's quite simple, really: it has nothing to do with a lack of empathy or selfishness (nice strawmen by the way). It has to do with pragmatism.
That pet is non-sentient, literally a creature of instinct. It can only be what it is; nothing more, nothing less. It is neither guilty nor innocent; it will act in accordance to instinct at all times.
You are a human being I do not know. That means I have absolutely no idea what kind of person you are; what you've done or what you could potentially do. I do, however, have history and society as precedents, and they tell me this: most human beings don't deserve being saved over an animal I happen to hold dear. Why? Look at a damning list of humanity's flaws:
- Acupuncture, chiropractic, and other "alternative medicines" that lack backing empirical evidence are touted as legitimate, which is moronic at best (i.e., it does nothing) and downright harmful at worst (i.e., people who develop arthritis from chiropractic, cancer patients who abandon regular treatment in favor the "alternative"... and then die).
- Opinions and facts are not properly distinguished by most people, who insist that everything is subjective, nothing can be right or wrong, and use that to make entirely non-subjective claims that crumble under thoughtful scrutiny (e.g., "homosexuality is wrong," "Smash Bros. Brawl has depth," "cops need to leave speeders alone and focus on real crimes," etc.). Speaking of which...
- Thoughtful scrutiny, aka critical thinking/skepticism, is a woefully under-practiced, under-utilized skill that a) would put such aforementioned chimera in their place (i.e., filed under BS) and b) actually comes under attack by fundamentalists who can't stand that their views -- which they couldn't prove valid if their lives depended on it -- don't sync with reason.
- The religious. Not religion itself nor secular practitioners who view religion as a personal thing that shouldn't affect law, but those who think unchanging, inflexible dogma is any sort of ideal way to view the world or live one's life.
As a human being I do not know, there's a pretty strong chance you fall under at least one of the above. And while you might not, when put in a situation where it's either you or a pet, that pet gets saved. Unquestionably. Without regret. Without remorse.
If I DID know you, that would likely change; I'll always save someone I know and at least marginally respect over an animal.
