This is repetitive and harkens back to horses beaten dead more than three months ago, but I thought it might have the virtue of succinctness on the issue. Either you believe it cannot be wrong, or that it can be wrong but is still preferable to its opposite. If you believe it can be wrong but is preferable to its opposite, then either you have a reason for your preference or you do not. If you have a reason for your preference, then let this reason be the new belief in question, and return to step 2. I claim that there is no way to stop looping back to step 2.
Justification never reaches a permanent stop.
