God has a rule; the penalty of sin is death, but the gift God gives is LIFE....ABUNDANT LIFE. HE MADE HIS ONLY BEGOTTEN SON TO BE SIN...."FOR US".
All men die, it makes no real difference if God decides some should die a little sooner or later for that matter to suit his purposes. But what about babies some may say? Maybe God did them a favor by removing them before they sinned. One thing is for sure, when we sin God only owes us judgment.
why would the creator of all things insist upon the slaughter of animals
Maybe because "all flesh had become ruined" on earth? Genesis says that only Noah was "perfect in his generations". [Reference to DNA?]- Gen. 6:9 ASV, KJV
Genesis tells us that man was wicked and that every imagination of his heart was evil. This seems to imply that man imagined to corrupt the earth and all that lived on it - and he apparently did all that he imagined to do. Note that verses 11 and 12 say that the earth was also corrupt and that all flesh had corrupted his way. Man did that as a result of Watcher and Nephilim influence. Note what the Book of Jasher has to say about this:
And all the sons of men departed from the ways of the Lord in those days as they multiplied upon the face of the earth with sons and daughters, and they taught one another their evil practices and they continued sinning against the Lord. And every man made unto himself a god, and they robbed and plundered every man his neighbor as well as his relative, and they corrupted the earth, and the earth was filled with violence. And their judges and rulers [the Watchers] went to the daughters of men and took their wives by force from their husbands according to their choice, and the sons of men in those days took from the cattle of the earth, the beasts of the field and the fowls of the air, and taught the mixture of animals of one species with the other, in order therewith to provoke the Lord; and God saw the whole earth and it was corrupt, for all flesh had corrupted its ways upon earth, all men and all animals. And the Lord said, I will blot out man that I created from the face of the earth, yea from man to the birds of the air, together with cattle and beasts that are in the field for I repent that I made them.
And all men who walked in the ways of the Lord, died in those days, before the Lord brought the evil upon man which he had declared, for this was from the Lord, that they should not see the evil which the Lord spoke of concerning the sons of men.
And Noah found grace in the sight of the Lord, and the Lord chose him and his children to raise up seed from them upon the face of the whole earth.
- Jasher 4:16-21 [emphasis mine]
and in the Book of Enoch:
And all the others together with them took unto themselves wives, and each chose for himself one, and they began to go in unto them and to defile themselves with them, and they taught them charms and enchantments, and the cutting of roots, and made them acquainted with plants....And they began to sin against birds, and beasts, and reptiles, and fish, and to devour one another's flesh, and drink the blood. Then the earth laid accusation against the lawless ones."
The book of Jasher is not inspired but is a Jewish history book that is quoted three times in the bible. The Book of Enoch is likewise quoted in the bible.
