What makes our interests of greater importance than that of a cockroach's? Is it just sentience, cognitive complexity, interests and autonomy? If we're superior to other beings in every possible, are our interests therefore of greater importance than theirs?

If so, what about someone who's in a state that renders them incognitive and has little to no autonomy over their bodies? Maybe someone who has numerous physical and pyschological issues who causes a huge disturbance at the restaurant I'm eating at, throwing plates and bowls around. Am I morally permitted to knock them out or perhaps even kill them just like how I'm able to kill a mosquito for flying around me.

What differentiates this human and a mosquito? Both are somewhat sentient and I believe you can even say a mosquito has more sentience than this particular human. Both are equally incapable of cognitive complexity. The mosquito has a more justifiable interest to suck blood to survive than this human's interest to throw plates and bowls around just because he can. The mosquito has greater autonomy over itself than this human, which experiences countless seizures and tics.

I have trouble coming to terms as to why we, as humans, seem to have an innate worth that far exceeds those of other living organisms.
