Sinners who kill innocent children are among those whom God condemned as "better never to have been born".
I believe there is only one unforgivable sin...I could be wrong tho.
Actually he referred to all sinners in such a matter.
So if taken in your context I guess that it would be better that you would not be born as well.
However, this is why we refer to people as "Born Again." So it's to our benefit that all sinners no matter the sin are able to be redeemed.
It's not up to you who should and shouldn't be allowed to go to heaven. Only God's judgement decides.
True. This is very serious business. A mortal sin, spiritual death. Jesus, save us.
