I think the Father Up Above, has made it very clear, in the Book of Revelations, that He alone can pass judgement. And this is based on what he is able to have access to, and what we do not have access to, in order to have that authority to pass judgement onto others.
In Johns; Book of Revelations 2:23, God revealed to Him:
“And I will kill her children with pestilences and all churches will know that I am He who searches the minds and hearts; and I will give to each one of your according to your deeds.”
We must keep in mind that when we walk on this path, that we call “life”, we can only hold ourselves accountable to the things we say, do , and think. And God will expect that of us. We can not change others in these aspects; only God can. In the end, however, God will ask us, as individuals, for all the things we did, while living on this earth, and see if we followed His Ways, and understood His Word.
So remember, judgement is not ours, but God’s alone. God gives each of us a window to peak in to His Widsom, through the lessons we learn in our life paths.
