You're not wrong, but there's a kind of irony in it when you talk about ending humanity because of it. There's a lot to hate about humanity if you have humanity and have human values. There's nothing objectively wrong about being cruel or destructive or dishonest or greedy or abusive or murderous and I imagine most hypothetical alien species would look at those things and say "what's wrong with any of that?"

But because humans evolved as social creatures and our survival depended upon trusting one another, we're constantly trying to judge ourselves against values that can't actually be met. So we look at ourselves and say we're a really horrible species, but that statement only makes sense because ironically we're a really glorious species that's fabricated these completely irrational things like love and compassion and empathy and honesty and sacrifice that no other species has (though many other social species do have bits and pieces of them).

And we'll forever hate ourselves for not being able to live up to our own values.
