Not universally, but base Fi have high compassion, all Fi types have it good. What you've described clearly reminds "beta style", more STs of beta. Besides theory, I communicated with ESI to understand what they can. Base Fi are very kind people (in my understanding and perception of this, at least). Such cruelty is doubtful for them. It's possible (as everything) for ESI, but with low probability.
> I guess you have to believe this if you are going to end up with an ESI now.
Seems I go there. And not me started this. Family "tradition" and some circumstances. Formally I'm still choosing, there are no relations but I feel them in the closest timeline (this year), and seems my heart supports this. Ni-imagination may mislead me, though. If it's not "just dreams" and as I'm idiot in F region this may lead to a marriage with almost unknown woman with understandable issues of semi-duality. *sigh*
> She didn't know any other way and thought she was doing the right thing.
A girl which I typed to EII said that to heal her shyness her farther send her to boxing training. I think it's same firm "beta style": if he'll survive it - good, not - also good. Damn stupid behaviorists-amateurs.
> I think she had a sadistic streak because of what she went through.
To be sadistic for base Fi is like to don't care about objective facts and truth for base Te, or to don't like fantasy for base Ni. It's almost impossible. That someone made her pain in childhood can't change the type's essence.
> If I had asked my mother earlier I would have gotten a better understanding, in my native language
What is your native language?
> She walked in the house and her grandmother was just sitting there.
You have interesting family. Mysticism of my ancestors (which ones I know) is limited by grandmother which liked to tell fortunes by playing cards (like seems many do) and her farther which played a little with witchcraft. There was probably a line with many priests, as one of my ancestors lines could be close to head of Russian church since 17th century (some were his guards, others could be priests using this familiarity - not bad "job" for those times).
> I don't have a problem with you, my sister, or my mom, calling it god since that is only a word people use for source energy or stuff they call "mysterious" and don't understand.
Energy, information, power, - anything you may imagine and to believe in. God in monotheism is used in the sense of Creator - the source of creation, of everything. All understanding is only model which is comfortable to use for our kind of monkeys. We'll get more knowledge and will evolve, our understanding will be changing until we are.
God conception is just practically useful. You may decline it, while you'd could to get profit from it.
> People can form their own opinions based on their own experience.
sure. you may try this model and such to get new experience
