A fair amount of problems would disappear. The thing is though, humanity is incapable of getting rid of problem makers. Mainly because we are all problem makers to one degree or another. Mankind is capable of many things, but making this world a utopia isn't one of them. As history so clearly teaches us.
Well it doesn't have to be Utopia ru. Just better than it is. I honestly believe some folks make it their life's work to harm hurt wreck destroy crush crumble obliterate. That's all they're good for or at least all you see them do. Defective brains for sure drive them to do that. Just get rid of them. Breed them out however we can like we did Polio. Treat them as if they are a disease which in fact they are. Playing God am I? I suppose I am. What could it hurt? Thank you for your reply ru! :)
