Realist,
That is what a disciple does. Paul had to deal with James, and the Christians in Jerusalem who nearly had him killed but he did not give up on them. But the choice is yours of course. Just how we continue in the faith after leaving such evil men can only be our decision to make.The rule is:
Jude 1:23 And others save with fear, pulling [them] out of the fire; hating even the garment spotted by the flesh. 24 Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,
Joseph
