Should we be friends with an evil brother or sister who walks disorderly?

“Therefore brethren stand fast and hold the traditions which you were taught, whether by word or epistle. And if anyone does not obey our word in this epistle, note that person and do not keep company with him, that he may be ashamed. But, do not count him as an enemy, but, admonish him as a brother. “Too many of us as Christians are afraid to call out our brothers and sisters when they do wrong for fear of losing their friendship; but scripture is warning us to admonish them.
