Honestly, no matter what JA is one of those people where some was not enough, more was not enough...there was never enough love, attention or caring. She had certain ideas of how love was shown, getting her way all the time, nothing she wrong should be brought up it should always be forgiven etc. She definitely was not able to receive 'love' in its truest form. The only way her parents could show her how much they 'loved' her was to believe everything she said, think everything she did was perfect and just give her what she wanted. Because they didn't do that it was that they didn't 'love' her. I bet a lot of those screaming/rage calls were about things that JA wanted but her parents were saying no.
I don't fault her parents for everything. Sometimes parents do the best they can. They may have thought at a certain point, maturity would kick in and she would grow out of it or something. She definitely needed help, but its possible it was way too late by then.

Sometimes there are just bad seeds in the world and there is no reason for it. Not because of parents or anything else.
To quote from a movie:
Sometimes, some people just want to see the world burn.
