In my opinion, the logic is quite simple. While its a controversial topic, but in the end, I would say there is simply more sufferings in this world than enjoyment, more discomfort & inconvenience than pleasure, if you were to weigh it on a overall scale. From all species involved (humans/ animals), and I of course don't have all the data and statistics, but just from overall observation during the few decades I've been on this earth.
You see corrupted governments, wars, conspiracies, hunger, disease, slavery, conflict with religions/ beliefs, murder, theft, crimes, prisons, divorce, child support, mental & health issues, suicides, disabled, betrayal, cheating, scams, pollution, nature being damaged for capitalism, lots of on-going conflicts, natural disasters, animal cruelty, drugs, bullying, torture, harassment, illegal stuff, politics, literally everything about money, etc.
Just think about for the average human, how much effort is involved to surviving just 1 cycle of life. From 20+ years of school, 50+ years of work, endless chores/ duties/ errands, relationship stress with friends/ family/ lovers, confidence and self-image, 3 meals a day, daily personal hygiene, endless commuting, endless thinking (planning, pondering, analyzing, pivoting, worrying, brainstorming), potential loneliness & emptiness, depression, anxiety, break-ups, keeping up with society, peer pressure, putting on fake mask, competition, staying safe and protecting ourselves, constantly needing to be occupied & entertained to not go crazy, facing death of loved ones, funerals, hospital visits, surgeries, therapy, medication, responsibilities, financial stress, taxes, legal related, etc..... then finally our own aging, declining and death.
Also just think about.... for just 1 single human to survive its average lifespan, how many animals in total need to die to support the daily meals of just 1 single human. Seriously, just do a quick rough estimate. Many thousands of animals per single person?? And think about the amount of waste/ garbage just a single person produces over their lifespan.... and humans (or surviving creatures in general) are actually gross. Do you know the amount of piss, shit, hair, etc. a single individual produces over a life-time? Including all the other gross liquids, puss, shedding skin, etc. that comes out of just a single human body alone. Now when you multiply all this by the billions, humans just becomes the #1 parasite and virus on this planet, constantly needing so much resource and energy to stay alive..... but ultimately just to rot and die in the end.
Of course this topic could be debated in multiple angles, perspectives, etc. And of course, its all part of natural causes, and yes, there are also happy and fortunate people in the world, there are also positives, along with sunshine and rainbows, but what I'm saying (including the OP @Peaceful_Sam ), is just imagine a fair amount of this craziness & headaches, could of been reasonably avoided, by simply a PENIS not ejaculating a SPERM inside a VAGINA....... that is all we are referring to lol. Of course we can't be 100% correct, but just sharing a different perspective as to how a lot of life's struggles could of been prevented by simply not so easily reproducing. People can of course still reproduce, as its human nature, but we just suggest most people be a lottttttt more cautious, compared to how the average person usually approaches this as something very simple, because the world is indeed a complicated place for the most part, thus is why ALL of us on this forum are looking to catch some sort of shiny bus
