We are one species of many on this planet.
Of course we are "better" and smarter, but suffering will still exist. With us or without us.
Maybe another species will even evolve and become as intelligent as us. My favorite are monkeys ;).
We also don't know what comes after death.
Nothingness is a wishful thinking of some people, but at the moment it is not a fact because we do not have reliable knowledge about it.
Another thing is that we on this site often have a distorted perspective on such matters.
Our point of view is not always correct.
For me, antinatalism is such an example.
For me, antinatalism is naive.
Personally, I also do not feel passionate hatred towards all of humanity (of course, to put it mildly, I don't wish anything good to some people).
I don't want to take away other people's opportunity to make their own decisions.
