Is kingdom animalia some magical line in the sand? Are we not okay with killing mosquitoes, bedbugs, or other (harmful) pests?
The world is much more continuous than discrete, and any hard boundary is going to be arbitrary. I would guess the current median line (meaning 50% of people would be okay with vs against killing) is somewhere around small rodent, and unlikely to deviate far from that in the near future.
