I still don't agree all states are negative or positive, as I believe there is a negative state of being. But I do agree there are inevitably people whose lives are more negative than positive. Therefore, by continuing the species of human existence we willingly impose this on those individuals as a form of torturing the innocent.
Yeah this argument is potent enough and I don't know what the counter-argument to it should be.
It becomes a matter of choosing one of the following:
We acknowledge that by continuing the species we know that however few certain individual's lives will be more negative than others and this is a form of torture to the innocent as they wouldn't wish to exist in such a life, and we imposed this upon them without allowing them to leave it (suicide is not permitted to even these individuals as a sense of "moral torture"). Meanwhile, we acknowledge in no circumstance is it justifiable to torture the innocent. Therefore, it is morally wrong to continue the species.
Alternatively, we believe it's morally acceptable to continue the species knowing however few that innocent individuals' lives will be more negative than others and how this is a form of torture, since if one's life is more negative than positive, they wouldn't wish to exist, and we impose this upon them. Therefore, in order to avoid the continuation of innocent people being tortured by lives that have more negativity than positivity we will enforce the discontinuation of the species through anti natalism. We acknowledge that by doing this many will suffer a lonely ending to existence and the economy and many of its sub parts will crumble into anarchy and a terrible ending to the world as less and less survive and manage to maintain society as it crumbles from beneath them. in this way the last survivors will be in a sense of torture and all of those who lived their lives even happily without any family that to them may have felt fulfilling. Ultimately, we acknowledge that it was not the people who will be suffering this lonely ending and destructive ending to society as it collapses with no one to fill the gaps as they once did. Therefore, this will be a sense of innocent torture of those who did not create the problem of an immoral existence and that by undoing the immoral torture we will be causing immoral torture. We also acknowledge it is not justifiable to solve evil with evil, and therefore it is unacceptable to torture the innocent as they were not the cause of the problem.
Though, perhaps it would be justifiably permissible as it would be a limited time of acting in an immoral sense but discontinuing the eternal immoral existence.
In essence, antenatalism is determined by a person's belief of whether it is justifiable to act in an evil way to destroy a greater evil.
But then a new problem arises on top of this one. The moment that we say it is permissible to act in an evil way to destroy an evil that is greater we are discussing the greater good. The greater good was used by Thanos, Ultron, and the Nazi's from their point of view. We most certainly acknowledge that we do not want to become them. Therefore, it cannot be justifiable to act in an evil way to destroy a greater evil. If it cannot be justifiable to act in an evil way by torturing the innocent by using enforced anti natalism which would inevitably cause ruin and destruction to the city of those who are the last people to survive as economy and jobs are lost and the city is in ruin as there are no more employees to continue running it and maintain it as it rots with those last survivors who may end up dying from disease and starvation. Therefore, in order to avoid using the greater good which is ending the eternal immoral existence by causing a limited time immoral act of anti-natalism there is no solution to avoiding the immoral act as the only solution to defeating the evil is with evil and as we will not use evil there is no solution but to maintain existence alongside it.
