We are all his children. Too bad He made it so half are below 90 IQ, and breed like rabbits.
So you're saying God made a mistake.
I would like to think He created us through evolution to be smarter, stronger, better looking, with the genetic crowd intolerance, to be able to live happy, joyous and free, sustainably and understanding His Laws and giving Him Love as He gives it to us. Evolution itself has been altered by human over-compassion and over-tolerance, and the developed crowd tolerance. This stuff goes back to some false religious beliefs, and failure to replenish the Earth or know the limits God set. Humans were their own predator, and perhaps He wants Those that can live sustainably and understand His Laws to kill off the dumb over-breeders, the greedy(and polluters), and the crowd tolerant. If we don't, then humans will go extinct and God will have not had His wishes for us fulfilled. 500 nukes to the world's slums, including our own, would be a good start. (50% of nuclear winter threshold)
Allowing extinction or causing it by over-breeding and not being green, would be the biggest sin possible.
