God did make us to be awful. He MADE our human nature, our DNA's, the way we think, our psychology. He made us to be awful, cruel creatures. Human experimentation has shown how human nature is naturally evil. The Stanford Prison Experiment shows how when human beings are put in a position of total control without being restricted in what they can do, a majority turn into evil controlling people and lose their morals. Power corrupts and absolute power corrupts absolutely. Look at how the Japanese Unit 731 did terrible medical experiments of unwilling test subjects. These medical experimenters were put in a position of total power, and the result was prisoners being subjected to vivisections without anesthetic, blowtorches to the body, chemical experiments, frozen and then unfrozen, tied up to wood beams and fired at with tank and motor shells, then treated to figure out the best way to deal with such wounds. The list goes on, and many people died. We would not have such medical advancement right now if such tests weren't don't on live human beings, but was the torture of so many people worth it? It would not have been worth it if even this happened to only one person. We have advanced with our medical science due to forced human experimentation, not everything can be learned through guinea pigs and lab rats, and even then torturing animals is wrong.
It is surprising that we have not destroyed ourselves by now. We, human beings, are our own worst enemies. Not natural disasters, supernatural forces, extraterrestrial life, or anything else. It is natural for us to hate what we don't understand. Look at how those with down syndrome or other mental disorders are treated, a very large majority of the population looks down on such people with disgust, because we usually hate things we don't understand that are different. Human beings are generally not accepting creatures.
It is a fact; God created us to be selfish, cruel, controlling, and many other things. It is in our genetic make-up. Who created genetic make-up? Only God.
