Bad guys turned informer. Good guys didn't - no matter when, no matter what.
Anger is always concerned with individuals,. . . whereas hatred is directed also against classes: we all hate any thief and any informer. Moreover, anger can be cured by time; but hatred cannot. The one aims at giving pain to its object, the other at doing him harm; the angry man wants his victim to feel; the hater does not mind whether they feel or not.
On that road of the informer, it is always night. I cannot ever inform against anyone without feeling something die within me. I inform without pleasure, because it is necessary.
