Actually, doesnt need to take their consent to know its hurting them,
same as we know step on peoples foot will hurt them. It just need an understanding.
if only people just think about the poor baby instead of their own before bringing it to his world but sadly most people dont
The only reason people bring baby into this world is only to fulfil their needs, it isnt for the babys own sake.
the reason is either to take care of them when they old, fulfil social pressure, improve status in social/boost about it, to work&help them, to fulfil their expectation/make them proud/improve/their life, carry their legacy/obligation, bind with their lover, entertain them(babies are cute), accompany them, etc
While for the baby.
It imposed: certain death for them, dying, aging, body deteriorating, getting sick, pain sufferings.
Some babies even get abandoned, get family abuse, broken home, family neglect unsupportive, parents cant provide/bad parenting, and the list goes on
tons of threats from transmissible disease like COVID&many other, incurable diseases, mental disease, genetic disease, deadly diseases, stress
accidents, natural disasters,
criminal, burglar, killer, bullies, harm from other people, the list goes on
certain endless burden for them to fulfil. Work issues, taxes, making money until they die work all their bones to make lots of money or they wont get to eat or buy their needs n get insult from society, fulfil career, social pressure, family pressure, love issues, lifes conflict, fights, the list goes on.
So even from that we can already calculate tons of disadvantages for them and how its only for the sake of other people that they need to be brought into this cruel world. How is it not selfish?
i understand what you mean n i dont mean to judge. But its just VERY SAD AND CRUEL to impose those tragedy to innocent babies, im just questioning how can people not care about it but instead glorify it.....? It truly baffled me and i find it ironic 
if only more/all peoples realize it there will be less sufferings
But at the end it all comes down to ego. People just need to keep bring new babies to fulfil the burden. So the evil vicious circle will never end
It's impossible to take the consent of the baby before bringing him or her to life. I think we Can do nothing about it , but to respect people's decision in either to create more humans or not.
True there are many abandoned children who suffers and no one care. thats example of selfish mindless breeder. But some keep breeding and bring more sufferings.
Why can they just help and take care of the baby that already born instead?
I just think it's funny when you look at pro lifers then look at orphanages and then look at the overpopulation problem.
Forcing someone to give birth to a baby no one wants or even willing to take care of sometimes into a world that doesn't need more people. How about we take care of the ones we already have instead of forcing someone to give birth just for the sake of having one more kid people don't even want to pay taxes to care for?
