Having kids is unethical at it's core if you think about it. yet ppl rationalize their instinct, they use it to escape the possible awareness of purposelesness of their life and actions. Only strong can face the harsh truth, and only strongest doesn't off themselves in the process. It takes quite some balls to acknowledge the reality and hidden workings of it. Better not to, probably, like a cat or dog, just procereate and die with no conscience, as the end result is pretty much the same.
I find it funny how many ppl are not self critical, I mean - when I look around I see quite some unlucky ppl, some short, some deformed in various ways, bald, ugly, unhealthy from a get go, from dysfunctional families, with no real sense of how to raise a strong individual that will suffer as less as possible, etc, etc.. yet somehow... majority of them justify their urge to procreate, without even thinking of what they will transfer to these new bodies and "souls".
