>>2938833Intrumentality can either be a gift or a curse that can further deteriorate her volatile nature. The ending made it as vague as possible in the direction either Shinji and Asuka take as people. Its up to them if they don't want to hurt others anymore and are willing to make sacrifices. Asuka has yet to show she is willing, but we'll see.
If I'm to be honest, I think she ends up addicted to drugs and sex and commits suicide. Shinji however, feel in love with Kaworu so there is hope for him.
