The books (since they all share the old testament in one way or another) talk about it, us being good shepards and responsible for all beings. Just a little, but it is there. Somewhere in the beginning.

It’s just that we’re assholes and if something doesn’t fit our narrative we ignore it.

Just like all the books make killing crime no 1, but we go “yeah, no” when it suits us. (in war you may kill because i say so and you may kill that Israeli, westerner or arab because they are subhuman unbelievers/desert rags.)

The commandments are very clear and there are no exceptions possible according to the book. But we made those up anyway. Which is weird. Here we have the guiding principles of being, given to us by god and we choose to disregard them. Sometimes even in the name of god/allah/Jahweh.
