I think most people would say “you thought you did something wrong when you didn’t”. — khaled
Potato potarto. It doesn't affect the point. It seems clear enough that our blameworthiness is determined by what we think we are doing, not what we are actually doing (not saying that has to be the case, just that it in fact seems to be). If I attempt to kill Mrs Jones by giving her substance x - a substance I think will kill her - but it turns out that substance x is in fact the very substance she needs in her system to stop her from dying - I am still in the wrong and blameworthy even though my act saved Mrs Jones's life. We can say that 'an' act of administering substance x to Mrs Jones would be right under certain circumstances (such as ones in which an agent knew that doing this to Mrs Jones would save her life). But my act was wrong, because my act can't be divorced from the intentions with which it was performed.
So, let's just be clear about most people. Most people are fully aware of how dangerous this world is and how much ignorance it contains. And most people believe that anyone they bring into being here will be born innocent. Yet they do it anyway. Now that's wicked. You do not have to have any view about life's purpose for that to be wicked. It is sufficient that one believes one is bringing innocent beings into this world, a world one is aware is dangerous and full of ignorance. The fact that, in reality, those who are brought into being here are not innocent and deserve everything they get is neither here nor there.
What about those who believe that God exists; that none of us have been created; that this world is a prison, and that everyone who comes here deserves to come here (and have arrived at this belief responsibly)? Let's first be clear how many people satisfy that set of criteria. Me. I think that's it. Just me. Is it morally ok for me to procreate, given my beliefs?
No, I don't think so. First, consider that I think everything that happens here is just. This is a prison, and we deserve to face the risks of harm we face, and we deserve our ignorance. That conclusion is, I think, inescapable, for reasons already given. So that means that no matter what I do to someone else, that person deserves it, and no matter what anyone does to me, I deserve it. Now by your logic, that means that here all is permitted - that I have no moral obligations, for no matter what I do to someone else, that someone will deserve what I do to them. That is what you'd conclude, yes? You'd think "well, if everything that happens here is deserved, then I can do what I want".
But that's clearly not the case. I - we - have moral obligations to behave in some ways and not others, even though it is not possible for us to treat others in ways they do not deserve.
Why? Note, the issue is not 'whether' this is so, for it so clearly is. The question is 'why' it should be. Why should we treat others 'as if' they are innocent, even if we believe, like Pangloss, that anything and everything that happens to anyone here is for the best?
Rehabilitation. A convicted murderer who undertakes to kill other convicted murderers is not fit to be released back into the community. They've missed the point of their imprisonment, which was not for them to punish others, for for them to be punished and to learn how to behave among those who are 'not' guilty of anything. (Why else does our reason tell us to assume others are innocent, not guilty; and to adopt an attitude of goodwill towards them?). And their behaviour is repellant. I mean, who the hell do they think they are? They are behaving 'as if' they have the moral authority of a judge and jury - that their job is to mete out justice. No, they absolutely do not have that authority and for them to think that they have it is, well, obnoxious. The people they're killing deserve to die; but their behaviour in killing them is no less obnoxious for that. Their job is not to mete out justice; their job is to do their time, understand how appalling they are, and undertake to change their ways. They are behaving 'as if' they themselves are innocent, when in fact their job is to learn how to behave towards the innocent.
Anyway, let's say I'm wrong about the above and someone who sincerely and responsibly believes that this world is a prison and procreation provides more cells for criminals is someone for whom procreation will not be wrong. So what? I mean, that just means it is morally ok for me to procreate. That's all. Antinatalism is not an absolutist position. Antinatalists do not typically hold that every conceivable act of procreation is wrong. Far from it: there will be lots of exceptions. They hold instead that procreation is in general wrong or wrong under regular circumstances. Now, most people do not believe this world is a prison and that their offspring are born criminals who deserve every risk of harm they face, do they?
