Why would he? He had no stake in us, and we have proven a threat to him and his protocols before. If cabal started shit with him he would’ve done something, and if he initiated first it would just be trouble for him, so he just stayed out of it.

Because MIDNIGHT EXIGENT was active. It is understood to be a protocol Rasputin activated during the collapse when he realized he couldn’t win against the Darkness. This protocol forces him to do everything possible to avoid enemies detecting him. He basically faked his own death and only became active once he was under threat or he needed to stop something from compromising MIDNIGHT EXIGENT. While it is active, his population protection protocols are disabled, as well as his moral subroutines. Basically? He won’t help us unless it helps him and he will do anything to avoid detection, such as killing hundreds of Iron lords who found one of his fragments in the cosmodrome. When the red legion attacked, he just let us kill them for him.

He is Russian so probably drunk on wodka 😁

It's unclear. He did fight [i]something[/i] during the collapse. However, Midnight Exigent required it.

Red legion was on Mars, he was probably dealing with them there
