None of that has anything to do with what you posted (the things I asked for scriptures on) I’m afraid.
Namely this;
Where does it say, specifically, that the higher the authority - the higher the crime, and hence the higher the punishment?
God is not “Anger”
God’s Justice is expressible through anger and wrath. But he is not “infinitely angry”, where as he is “infinitely loving” for example.
Isa 57:16 For I will not contend for ever, neither will I be always wroth: for the spirit should fail before me, and the souls which I have made. -KJV
Isa 57:16 I will not take vengeance on you for ever, neither will I be always angry with you: for my Spirit shall go forth from me, and I have created all breath. -The Septuagint
If an infinite thing (A) is in an infinite sized room with another infinite thing (B) where is the border of separation between infinite thing A, and infinite thing B in that infinite sized room?
And no dear friend, I am not ignoring any of his attributes. I am putting them in their proper context.
God is not Justice without Mercy, or Grace, or Love, he doesn’t express a single attribute without expressing them all; God is One.
When he expresses his righteous justice, it is out of Love - and Love is always for the benefit of the thing it loves, True Benefit, providing for the needs of the beloved, as well as satisfying the noble wants of that same beloved.
When you take Love out of the equation of Justice - you kill both Love and Justice. The same with Mercy, and Grace. You cannot have Justice without Mercy and Grace permanently involved and equally expressed.
You assume I have a presupposition. Please don’t assume. 
I’ve not ignored his wrath, or his anger. I’ve only presented that they are not equivalent to a drunken father beating his child ceaselessly for breaking the family vase - even if it was done on purpose.
It is unloving to eternally torture the prodigal child, and not even leave eternal room for him to return Home.
Until the wicked are made righteous.
Rom 5:19 For as by one man’s disobedience many were made sinners, so by the obedience of one shall many be made righteous.
You assume that I believe his justice is a slap on the wrist? God forbid! A “thousand years” (a long time, but not eternity) of chastening with fire is more than enough, unless one has no concept of mercy, and grace, and justice - and are only interested in revenge, or using God as one’s hitman.
Chastening until one is righteous, and made right is no laughing matter, neither do I laugh at it. Jail is fearsome enough without capital punishment being used in sentencing what is for the most of mankind little more than petty thefts, or at worst grand theft. Not everyone rapes, and murders, and has little girls chained up in their basements for frightening orgies. And for those who do, a trillion years is still not an eternity - but a trillion years is definitely a long time to be in chastening pain faced with the holy God who is an all consuming fire.
It doesn’t tickle the sinner when he’s faced with his own wretched nature, and certainly not when faced with the humiliation of having to repent for it. It doesn’t make me giggle when I’m even convicted of sinning, it certainly will not tickle the sinner in fire when it is being burned right out of him with nowhere to run, or hide - and the deeper he goes in trying to bury himself under himself the more it will burn and the hotter the purifying flame will be.
But he will be purified, just as you and I - who are no less as wicked as Satan himself are being purified.
Using your logic, you deserve the same exact punishment as the rapist. Even without the “slap on the wrist” statement.
If the wicked man is made right, there is no call for continued chastening, or vengeance. Unless one’s only aim was not remedial justice, but was merely vindictive revenge. Now I am not saying that you are all about revenge, but I am just showing you to the best of my ability what this eternal form of “justice” is in its practical usage.
If there is no remedy, it is merely infliction, if it is merely infliction it is not justice - it is revenge without room for repayment. That is cruelty. And a cruelty that under your logic; we all deserve. And if this is God’s justice, then this is exactly what we’ll get - saved or not. Because if this is God’s Justice which is inseparable from his love - then his Love is expressed this way also…and we are in deep trouble.
He is chastened until he is made right and repents, the family is restored, and there is peace, blessedness, grace, forgiveness, and good will between them. That is God’s Justice.
In other words; When the sinner is made right, and the family is made right, and everything wrong has been made right - Justice has been fulfilled.
His Mercy and Justice are thoroughly inseparable.
Because it isn’t Loving, and it is indeed overkill - because it is irremediable infliction without room for Mercy or Grace or Justice - and therefore it is not Love at all.
As for scripture, in truth you go not from scripture solely - you go from an interpretation of a translation of a copy of a copy of a copy of lost autographs…of scripture. Just to remind you. Because I too go from scripture, I have not built my beliefs on a man-made Babel. I only want to address this because of three reasons, and though you are apologetic about it those reasons are still there;
-
You assume I believe Justice is a slap on the wrist wink at sin.
-
You assume I do not have scriptural backing.
-
You assume I have not fully considered the whole attributes of God as far as my finite abilities are able to comprehend his infinite nature.
All three of these are falsehoods, hopefully not on purpose, but I tell you they are falsehoods so you won’t repeat doing them.
God bless you as well.
