The reason your views should be rejected is not because they turn God into a meany, but because they are unbiblical. We are to believe what the Bible actually says, and not in the misunderstanding of well intentioned men.
You first premise, we are all spiritually dead, made sinners by the one (Adam) is biblical.
You second premise however is unclear: Here is what you said. "And IF we cannot come to god by our own violation, dead in sins and transgressions..."
There is support for not being able to come to God "by our own volition" but no support that we cannot strive to come to God "by our own volition."
We, by our very natures, are at emnity/war with God, none seek after the Lord "of their own free will"
Your third premise, then goes completely off the rails, a total fiction according to scripture. Here is what you said, "IF all humans were thus by their own natures and wills bent on hell, Unlesss the Lord directly intervened to save some...
Romans 9:30-33 tells us of spiritually dead folks who were striving to obtain the righteousness of God, and so at that time, they were not willing for Hell.
When we are volitionally sinning, then we are willing for Hell, and we all sin. But even though we are dead in our sins and predisposed to sin, and we sin every day, this does not support the Calvinist assertion that at no time do we seek God. Again, this reflects my minimalist approach to understanding scripture. In Romans 7 we have Paul recalling how he sinned but did not want to sin, at least some of the time. This captures the reality of our condition. The "one size fits all" view of Calvinism is simply unbiblical.
Not a "fiction"... man, left to his own violation, "free will" will chose to walk in darkness, and will be bent on not obeying the Lord, or coming to Him, as our very "natural" natures preclude that...
Last point, you said: "What is so wrong , since NONE of us deserve anything from God other than Him judging and condemning us?"
There is absolutely nothing wrong with God having mercy on whom He has mercy. None of us deserve anything other than judgment and condemnation. All true.
So what would turn God into a meany. Calvinism where God predestines everything because He foreknows everything (according to Boettner) so God according to this Closed Theism view, predestines people to sin, then punishes them for the sin He predestined them to do.
God is NOT direct cause of all things though...
Knows ALL things that will/can happen, can intervene at any time he chooses to BUT...
Did not 'force" Lucifer to sin, or adam
Does not 'force " people to Hell
mankind still "free" to choose, just that w/o the Lord directly causing us to become regenerated/saved, will not come unto Him...
On the other hand, if He created us and allows us to be able to make choices autonomously that alter the outcome of our lives, then we are responsible for our sins and giving us justice is not mean, but just and perfect and good.
