But what about the complete depravity of mankind?
We're all debased and evil!
See, you're doing it wrong. It goes, "Everyone is debased and evil... except me!"
Or more precisely:
I am a good person.
You are alright.
He/she has some issues.
They are totally evil.
Do people really have that much of a problem admitting that they are bad?
Let's try logic.
I cheated.
People who cheat are evil.
Therefore I am evil and deserve punishment for my crimes against God.
That was easy.
I am evil and deserving of punishment.
