Define animal

animals don't express themselves with words. They don't sing.

Animals are needlessly violent, as in the word brute. They have no
empathy for others suffering so are able to hurt them for no reason.
They HAVE no reason.

Animals have no care for anything other than the importance of their
own pleasure and wellbeing: they have no understanding of morals, so
they murder and molest their children. They can't love, so have sex
without caring

To animals the first imperative is survival of the species, which means
they try to anihilate any other species in their way. But the
secondary, and often clashing imperative is that of territory, so it is
not unusual for them to kill their own species. Infact, animals put
more resources into defending/increasing territory than into feeding
those of their numbers who cannot feed themselves. Animals are
motivated by survival of the fittest, so will allow the weak ones,
those who don't fit in to die alone in the cold

Animals are unnable to think further than their own immediate
environment :

Animals kill for food; they think nothing of killing young infront of
their mothers. They do this even though they don't need to, even when
they're not HUNGRY, just because they like the taste and smell of
flesh.

Only an animal could force a mother to watch, singing as her young one
burns on a fire

Animals never learned how to make fire
