I'm pretty sure ghosts are evil, for three reasons: 1. They were forged in the black garden. 2. In strikes whenever the ghost decrypts something and you fight waves of guys, he always finishes when you kill all the enemies, kinda like seeing if you die or live. I'm also pretty sure he set off the alarm in that Sepiks strike. 3. If someone deploys a ghost and it is scanning or breaking into something and you hit it you will get a hit marker. I don't know, I guess I'm paranoid about having a robot inside of me.
