I do not consider him to be responsible for something men do. However, in his own words he set the general stage for alot of suffering and damage.
Genesis accounts relates of the language confusion at Babel. Reason to do this was men were united under one government trying to establish anything that came into the mind.
The confusion of the language prevented human enterprise to carry on united. Instead, different languages came into being, people no longer could understand each other. They started to spread out, thus giving rise to tribalism and nationalism. Religion was spread this way too, so all differences in religion found their origin there.
This "act of God" has caused a lot of suffering and pain.
.......if you believe any of it.....that is.
