Surely you wouldn't do such a thing, destroying the righteous along with the wicked - Genesis 18:25
Abraham's heart sank when God announced he would destroy Sodom:
He couldn't just stand there without trying to intercede on their behalf
Abramham trusted God's assessment of Sodom and he to be just and righteous
God said he would not destory the city if there were 50, 30, 20, 10 righteous left - Genesis 18:32
