I think it being at least partially purple actually is a big part of the joke of the card Making a note to fix Attack the Darkness.
If one of your characters have negative energy being, is the computer smart enough to not attack you? If one of your characters have negative energy being, is the computer smart enough to heal you?
I'd say no to both; the AI doesn't care what attachments any characters have. (i.e. moves frequently with Path Of Knives, attacks characters with Impenetrable Nimbus)
