Thanks--okay, that is different to an immature feeler... I actually wasn't trying to level out the playing field with my question, but was wondering if you were reacting to immaturity in all forms, as opposed to the 'feeling' side, which might just be incomprehensible to you at present.
But your views of immature feelers/thinkers seem to be linked by their stubborn refusal to see other points of view, whether the basis is from logic or from values. My guess is that your annoyance comes from the refusal to compromise and the creepiness comes from the refusal to explain?
People who act in unconscionable ways while saying 'they felt like it' creep me out too, but I doubt these behaviours are limited to feelers. Someone said it before and it's worth stating again - often 'I felt like it' is a crap excuse for someone who either, i) can't be bothered to rationalise their own behaviour, or ii) can't be bothered to explain their rationalisation to you. It's a very easy exit clause to take, because often, the 'uhh- felt like it' statement bamboozles the other person so much that they drop the subject or start focusing on that statement instead of the action that led to it.
That sort of statement could come from an F or a T - though ironically, it's MORE likely to come from a T. Fs generally want to either connect with you or to express themselves... so you'll more likely get a HUGE overexplanation (ie, a dreadful rant/lecture that will leave you running for the hills) or a flustered attempt at a rationalisation-that-barely-makes-sense than a brush-off.
I'm kinda thinking, in your example waaaay back with your policeman friend, that sort of response could have come from any of my TJ friends - spite is not limited to Feelers at all. My ENTJ friend would have taken great joy in giving someone a ticket for being an asshole. But -- and here's the difference -- if so inclined, he would have been able to give you an acceptable logical, rational explanation for his behaviour, which to me (as an F) would have sounded like pure bullshit.
I guess my point is that any type is capable of crappy behaviour, but I think some can simply explain it to you in a way that sits better with you, while others will not be able to... and it might simply be your own predisposition towards Thinking that is stopping you seeing from the Feeling perspective. I know some strong Feelers can find Thinking actions incomprehensible, but if they ratcheted down the Feeling somewhat, would be able to see from the Thinking perspective. If you truly want to understand the Feeling perspective, you'll have to let go your bias - at least temporarily.
Hopefully that made some sense!
