from what i understand on what's required for the good ending, you need to have no ally murders, i try my best to avoid my character being in any line of fire of my own attacks cause it never turns out good if they are.
When i was in the Item World getting Geo Chains to boost up the Bonus Gauge to level up some classes to unlock the newer ones one of my guys (well girl) i accidentally left on a geo panel when the chain started, she was bellow level 5 with no amour so you can imagine what happened.
anyway, i'm wondering if this counts as an ally murder

No, they do not.
