Antinatalism isn't inherently negative, it's a philosophy that questions existence. One doesn't have to be suicidal to decide to not have kids or to spare them from living in this world. There are couples, parents, even grandparents, that have come to terms that there was absolutely no reason to procreate. Antinatalists aren't just some sad ppl going through depression, the philosophy requires deep and critical thinking.

Occasional suffering isnt actually that bad like damn

How does one guarantee that a child will just go through "occasional suffering"?
