We do not have a record of Satanic meddling with humans from the fall of Adam and Eve to the flood. It may have been taking place with various individuals. We do know that humans degenerated almost completely to their basic fallen nature;

And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. - Genesis 6:5

The extermination of everyone on earth except for eight people tells us several things;

1. There is a limit to what God tolerates.

2. God can and does take what can seem to us as drastic action.

3. It is in our nature to completely degenerate.

4. Trusting in God is our only hope.

After the flood we have the first recoding of man's collective action.

We do not know if this process of collectivization was instigated by Satan or not, but we do know that God did not consider it a good thing;

It would seem that the prospect of human collective effort was alarming to God. In particular, unrestrained action driven by imagination. If we consider what humans were created for, we can see that uniting together to go our own way was not what God intended for us;

The world before the flood is a good illustration of what we accomplish apart from God on our own. If our imaginations run wild and we unite in collective effort, how much worse would be the result;

While we do not have a specific record of Satan stirring mankind to collectivize themselves for his use, it seems logical to deduce his involvement. Satan is unable to be everywhere at once;

In order for Satan to have any influence over humanity he has to get individuals to form groups that will act in such a way as to use social momentum to carry people in the direction he would have them go. His use of groups is designed to amplify his influence beyond what he could exert individually or even through the agency of the demonic forces at his command.
