i turned mira evil, but you cant avoid lightside points if you wanna jedify her,
i went neutral/ low lightside, went to nar shadaa first, went through did light and dark side things, to stay neutral/lightside, i did the dark side things with atton around, to get influence with him, and light side things with bao-dur, to get him influence, by the time i got to goto's yaucht, atton, and bao dur were jedi,
then after i was sure mira was on my side, i killed zez kai ell. Its easy to get influence with mira, you can get it all through dialogue, as long as u have 11 awareness.
