Yes.

We cannot accurately judge someone else's chances of salvation because we lack the information required for it (only the Final Judge has that information).

And we should know that we will be judged in earthly matters according to the stick we used to measures others in such matters.

God hates hypocrites, but we are not called to indifference for the moral state of our Brothers and Sisters in Christ. We are also not called to a lack of discernment, or moral cowardice.

Sometimes we are called to be prophets in our own time and place. To stand up and be counted. To say, "No, that is wrong."
