he wasn’t the real serpent, hes probably working under the real serpent and tried to cover the real serpents tracks
The question is why?
Spoiler
Because the serpent wants to be a bitch and kill everyone (messed up religious reasonings)
So the guy that shot himself, who confessed he's the serpent, wtf was he planning injecting a infected serum to a kid, setting a coordinated plan to contaminate the rainbow city? Why did he do that?
