Again, where is the harm here that would require revenge?Here are some potential examples:
(1) You get rejected by a girl and think to yourself, “I’ll show her.”
(2) You get cut from the team and think to yourself, “I’ll show them.”
(3) You get told you can’t do something and think to yourself, “I’ll show them.”
Are these completely foreign experiences?
If not, then universalize it: You feel knocked down by life where everything is going wrong and all your desired plans seem to be rejected.
