John Chrysostom, on Ps 49:18

“If thou didst see a thief thou didst run with him: and with adulterers thou hast been a partaker.”

“Most people, after all, do not simply give a verdict on their behavior from their own judgment but are also corrupted by the support of others. If sinners see everyone opposed, they believe they have committed some great crime; but if they see them not only showing no anger or irritation but exhibiting tolerance and joining forces with them, the tribunal of their conscience is then corrupted because the verdict of the majority supports their corrupt attitude. So what crime will they not attempt? When, on the contrary, will they condemn themselves and give up sinning unscrupulously? Thus it is essential that, in the case of people committing sin, they condemn themselves (this, you see, being the path to refraining from wickedness), and even if not practicing good, commend the good. The path to performance, after all, is willingness. Yet in this case, since there have been accomplices in crime, it is appropriate to apply the goad with great severity. After all, if evil flourishes to this extent even when reproved, and virtue, even when commended, has difficulty summoning its practitioners to the effort required, what would happen if these conditions did not apply?”
