Sure it was his creation, The perfect part of it was. The corruption came from another force. As did the evil that killed millions of Jews, and millions of Christians and just keeps on killing. We were perfect, but temptation and sin took care of that too.
And no, we aren't animals. But maybe you should be a god since you have all the easy remedies.
He is going to "fix it". First He's going to save as many souls as he can, you know. the part He created in his own image.
Yet you speak as if YOU have the answers, but your answers sound like something I'd expect any barbarian circa 4th century to say.
It makes no logical or moral sense to create a world of imperfect beings with strong drives in opposition to your commandments and then condemn a good portion of them to the void or to punishment because some of them don't or can't control their impulses. God created it, by your account, and if he knew what was going to happen he is fully responsible for all evil in the world. Even if you believe in Satan's effect, you are essentially setting up a duality and not a truly monotheistic cosmology.
Psychopaths are beyond redemption. And often they develop at an extremely young age--who is responsible for that and shouldn't, if there were a God who was active, ALL humans have equal chance at redemption and atonement?
That all said, it sounds like a big play for someone's amusement. Why create souls merely to try to 'save' them when you could have made a paradise and enjoyed ALL of them?
