Then there's one who told me she would like to put a certain criminal into a vat of flesh eating snails and grin while she watched them slowly eat him. Her ESTP husband reprimanded her, telling her that such an act of punishment would make her more evil that the criminal she so destested. IxFPs are capable of harboring secret hate and resentment, of outwardly taking abuse while inwardly planning revenge. IxFPs, usually have to be provoked, but they are capable of acts of evil, the same as anyone else. I think Stephen King does a good job with them in his writing. For example, the character in The Secret Window gets revenge against his cheating wife, INFP style. I'm not saying that's his type, only that what he does is the kind of thing I hear my imbalance INFP friend talk about. She can devise a trillion ways to torture someone, but thankfully, she doesn't carry them out. Probably because she lacks the opportunity.I could see that in these terms.
