You should check out the antinatalism subreddit(Reddit.com). This is a complex and philosophical subject. Bringing people into this world is something that some deep thinkers believe is immoral. Other people think it is beautiful. I won't state my beliefs so that I'm not belittled and bashed at by anyone, because I don't feel like dealing with that, but I do understand how you feel. Try to remember that it appears to be a biological instinct to have kids. People don't generally think it through(shitty parents included).
This universe is definitely very immoral in many ways(setting deep philosophical possibilities aside, such as coming here to learn spiritually). You can't consent to being born. You're born a helpless baby. You can pass on medical issues like migraines to your kids(hey, that's me!..I'm the kid). It's just all over the place, you know? People can get pregnant so easily. The drive to do so is just too strong for most people. Sadly, there is no way to morally overcome this. It's all just way, way too complex.
What I will say is that if people are going to be forced into this world, they should be allowed to leave it too, painlessly.
