For those who don't know who I am, I already know the answer to this.
It is impossible and stupid to think that good can be assigned to any person based on their merit. There isn't a reasonable equation to make it work. Whether my cannibal or any other, every person will commit enough "bad" that no "good" they do can cover it enough to make them "good" again. We're all "bad" and if we're honest we know it's true.
That is where Christianity distinguishes itself by fully relying on another, Jesus, who through a perfect, sinless life, and a sacrifice, can wipe the "bad" from any person based on a repentance and reliance on Him. A gift of grace, through no merit of our own. We don't deserve it and we don't earn it, only can accept it.
It simply can't make sense any other way. Ya know?
