Problem with Calvinism is it inadvertently makes Evil holy attributing way to much divine power to Evil to the point of even calling GOOD things EVIL or having love that is not love at all, or accepting Evil as natural creator 2ndary God.
Things created by God are natural, hence they are in nature. Things created by God are Good, ACTUAL GOOD.
There is no "EVIL NATURE" no "SIN NATURE" there can only be a corruption and abomination of TRUE NATURE as God set forth.
To say there is a SIN NATURE or EVIL NATURE is to wave the Devil's flag in victory its the eternal "I told you so" or "Takes one to know one", on GOD.
Its the idea that Evil is not defective which is wrong. All evil is defective, it sins, misses the mark, it is corrupt, it is unnatural, UNnatural.
Suppose YOU are Totally Depraved, We'll say well It doesn't mean he is as evil as he can be, like runs around murdering and raping like a lunatic. It means you have a lack of "SPIRITUAL" Good a complete INABILITY to do anything Good before God.
We begin to see the SPINNING calling Good Evil and Evil GOOD. Buddy let me tell you, If you have no spiritual GOOD and are completely unable of to do anything Good before God you are absolutely indeed AS EVIL AS YOU CAN BE.
There is no such thing as 2nd class Good. When Adam ate the fruit was that murder and evil as he can be? Every sin is like attempted murder on God.
There is other "Good" News to being totally depraved.......you can't get corrupted worst. You can't fall when your laying down on the ground you actually have to be somewhere up the ladder to fall.
Everyone on default is a Devil Worshipper.
I could say hey everyone is "SPIRITUALLY" Dead. An Evil person's heaven is he can sit hear the terror and suffering of millions of souls, like music to his ears. If that sounds a lot like hell that's a good thing. Evil is out to destroy kindness, love and compassion. Its the same hell even if you think heaven is some kind of sex cafeteria have what you want.
Any "Good" that doesn't glorify God is EVIL and should be called evil rather then good.
" But for good to be diminished is an evil, although, however much it may be diminished, it is necessary, if the being is to continue, that some good should remain to constitute the being. For however small or of whatever kind the being may be, the good which makes it a being cannot be destroyed without destroying the being itself." ST. Augustine
Mankind was wounded at the fall with Adam and Eve. But if you say all capacity of Good (true good, spiritual good for God, not "FAKE" GOOD) has been destroyed then the being itself is destroyed.
At moment of your soul's creation, never mind your conception, Total Depravity says you come DEAD. You can't fall, you start way down there, You don't start born, you start dead.
This is why BORN AGAIN and RE GENERATE don't fit here. Because it implies Life prior and prior generation.
If it was the first time scripture would act like it.
