Childhood example (since that's where all my examples seem to be coming from): I did something wrong, and it was horrendously wrong because I feel abnormally bad about it, so I want them to know why I did it, so that they have all the information before they start to lecture me about the situation. Maybe I took some correct steps before going into the incorrect ones, so they won't have to lecture me as much or in quite the same way. Maybe they'll have advice for me on how to change my mindset about it, if it was my mindset that was the problem. Maybe they'll be able to validate me just a little, make me feel better, before the lecturing starts. Either way, from my viewing of it, being able to look inside my head and change the way I mentally approached the issue will keep me from making the same mistake again, as opposed to just lecturing me on the events (which I'd think were a given!), attributing all responsibility to me, and telling me not to do it again. Not to mention that there's always the possibility that I wasn't 100% in the wrong, because either my process wasn't 100% wrong, or my intentions were pure. Of course, that sort of grey area is probably not something that Fe tends towards; like fidelia was saying, Fi is more live-and-let-live, so Fi would probably be more willing to call someone 75% wrong and attribute responsibility to several different parties, instead of just the one and 100% wrong. (I dunno, I'm BSing a little here.)
