I had tried to manipulate people growing up in my teen years as I had seen it done by a woman I was infatuated with who also happened to be the definition of a psychopath, but when I tried it ate me up inside. It's not a nice thing to do, lie to people, and even if you go about claiming it will make them better it just doesn't make sense. Why would you have to lie to someone to make them better? It's selfish, and shitty and crazy and people shouldn't do it. That being said I don't do it anymore. Shortly after I did I just couldn't bring myself to do it again.
Ask for competition, I'm not competitive, I can't be. People get mad at me when I win, and they get more mad when I lose. Some idea about I should feel bad for losing. I still don't get it. I don't like competition for that reason though, people always feel bad in the end regardless of the outcome from what I've noticed.
I do however use certain things I have learned that make people feel good or trusting when I meet someone or have been friends with someone for a long time and just recently started hanging out again. I'll hug people when I meet up with them, as it allows them to trust me and vise-versa. I've noticed it calms everything down, and if the hug doesn't happen in cases where it has never happened things are stressed. So I'll use those kinds of techniques.
I don't know if those traits in the negative would go hand in hand with any INFJ. I'd think that we need to be nice people else it eats us up inside because we recognize so quickly that what we're doing is shitty. I think you'd have to have something wrong with your sense of empathy and sympathy to do those kinds of things to people, and INFJ's from what I understand have a very prominent ability for empathy and sympathy.
