Let me first tackle the philosophical level: First, you insist on the impractical notion that it is only the suffering that counts and must be reduced no matter what. Being a intelligent fella you realize that the consequence would be the annihilation of all sentient life including your own. Since presumably you realize the absurd notion of this consequence you try to reclaim the validity of your argument by arguing that “not forcing others” is another crucial prerequisite in your ethic. (Regarding your own suffering and the ending of it you simply declare that “life is complicated”. Aha, so much for consistency. (By all means: be inconsistent in that case.)) But strictly speaking, you cannot force life on someone because that someone does not exist before she is alive. You can see it in your own comments. You talk about “forcing life on newborns”. But this is not true. Before they were alive they simply were not there. By definition you cannot force something that does not exist. Again: I can force you to give me your money but I cannot force something nonexistent to do anything. So you are back to square one: total annihilation of all life.
The same reasoning applies to your heroin addiction analogy by the way: The alternatives are not heroin vs. no heroin but heroin addiction vs. death. You see, you can without a doubt compare a person that is heroin addicted to one that is not and conclude the the non-addict is for some reasonable metric better off. But you cannot compare a person who is alive with something that does not exist. It doesn’t make any sense.
The philosophical nitpicking aside, what really strikes me as odd is your sole focus on suffering. In your picture you also “force the newborn” with high probability to having two legs, in- and exhaling air, and opening a bank account before her 30th birthday. And who likes that? But wouldn’t it be much more reasonable, as other commenters have pointed out, to account for more than just the suffering in the calculation whether a life is worth living? When you are in need for something, lets say food, do you only take into account the costs or do you compare the benefit you get from the food vs. its costs (the costs being the suffering in this analogy)? I mean, as a “life addict” yourself you realize that the suffering is sometimes not everything that counts especially when it is outweighed by the benefits you have by being alive. Don’t get me wrong: of course suffering is bad. But as you said yourself “life is complicated” and often you have to take more into account than just one single variable like suffering or the opening of a bank account.
It is of course your choice whether you procreate or not. But your argument against it might not be as conclusive as you might think.
