This view has led me to value mercy over justice in everyday life. I can't stand it when people feel the need to seek revenge. I always presume, indicative of my own tendencies, that whenever people sin, their remorse will be so overwhelming that it'd be unfair to come down *too* hard on them. I don't think "learning the hard way" is always necessarily through experiencing vengeance happening to you, although it may be in most cases, especiallt if you aren't an NF.
I have an extremely critical older sister and now I realise why I get so angry whenever she gives me a lecture on inadequacy; I cop it enough from myself and learn life lessons from my own guilt.
