Preferably keeping lethality close to the zero mark.

To leave a friend to suffer is to do them no favors. I say that because if Aeron does fully emerge, Shinji would likely suffer more then he ever has, especially if he ever regains control.

Hawk: thats what this group of Shinji's doesn't understand. This [i]Is[/i] the worst case scenario. Aeron has already interacted with their group. He knows names. He's most likely already begun his plot.

And from what I've read in that file, he should become greatly encumbered in his plots should Shinji gain a healthier mindset and environment. So though killing him isn't off the table, it isn't the end of days yet.
