The argument has a flaw
On this basis why didn't God save the thousands of innocent young holocaust victims some of whom were too young/didn't commit significant crimes ?
How do christians justify their God not helping innocents who were mercilessly killed in ww2 ?
The strawman is highlighted in bold.
Although the children are innocent in the sense they have never intended to commit no harm to a person. The vast majority of Christians believe that all children (with one/two exceptions) are all conceived with sin, so the death/suffering of the children would not be a fault on God's part.
Catholicism (majority) teaches this
If any one denies, that infants, newly born from their mothers' wombs, even though they be sprung from baptized parents, are to be baptized; or says that they are baptized indeed for the remission of sins, but that they derive nothing of original sin from Adam, which has need of being expiated by the laver of regeneration for the obtaining life everlasting,--whence it follows as a consequence, that in them the form of baptism, for the remission of sins, is understood to be not true, but false, --let him be anathema. For that which the apostle has said, By one man sin entered into the world, and by sin death, and so death passed upon all men in whom all have sinned, is not to be understood otherwise than as the Catholic Church spread everywhere hath always understood it. For, by reason of this rule of faith, from a tradition of the apostles, even infants, who could not as yet commit any sin of themselves, are for this cause truly baptized for the remission of sins, that in them that may be cleansed away by regeneration, which they have contracted by generation. For, unless a man be born again of water and the Holy Ghost, he cannot enter into the kingdom of God.

But I said the "vast" majority believe this.
With the Westminister Confession we ca expect to pick up a bigger majority
I. Our first parents, being seduced by the subtilty and temptations of Satan, sinned, in eating the forbidden fruit. This their sin, God was pleased, according to His wise and holy counsel, to permit, having purposed to order it to His own glory.
II. By this sin they fell from their original righteousness and communion, with God, and so became dead in sin, and wholly defiled in all the parts and faculties of soul and body.
III. They being the root of all mankind, the guilt of this sin was imputed; and the same death in sin, and corrupted nature, conveyed to all their posterity descending from them by ordinary generation.
IV. From this original corruption, whereby we are utterly indisposed, disabled, and made opposite to all good, and wholly inclined to all evil, do proceed all actual transgressions.
V. This corruption of nature, during this life, does remain in those that are regenerated; and although it be, through Christ, pardoned, and mortified; yet both itself, and all the motions thereof, are truly and properly sin.
VI. Every sin, both original and actual, being a transgression of the righteous law of God, and contrary thereunto, does in its own nature, bring guilt upon the sinner, whereby he is bound over to the wrath of God, and curse of the law, and so made subject to death, with all miseries spiritual, temporal, and eternal.
We can expect the same trend with Calvinism and Lutherism and other denominations.
so...if He is the one true ,omnipotent,benevolent God,then He should help/save innocent people.
All Christians (that I know of) believe that God does help/save innocent people, maybe sometimes from temporal harm but always from eternal spiritual harm.
There is a litany of bible verses illustrating this, the most well known would be John 3:16
For God so loved the world, as to give his only begotten Son; that whosoever believeth in him, may not perish, but may have life everlasting.
Another would be John 11:25-26
Jesus said to her, I am the resurrection and the life: he that believes on me, though he have died, shall live; And every one that liveth, and believeth in me, shall not die for ever. Believest thou this?
The term "innocent" can mean different things to different denominations.
