I’m someone who just started to read the novel of this, I’m a bit confused who the traitor was because my killed himself and goes finishing the stories solo. I’m talking about the traitor who wanted to kill all the top 10 so you can go to floor 99 in a one shot. I’m just curious who it is

Well they didn't really reveal it or rather its not definite, but they did say the Count (cat lady) was the betrayer. I'm not really sure cause it was said quite indirectly but the novel said the betrayer died by the demon King's sky-splitting sword strike or whatever it was; and the only missing person was the Count.
But then again, I think the author was trying to trick us. To me the religious guy is suspicious, since when they did the lie detection thing he said "sorry" (was a joke but I don't trust that) and "I don't wanna die by the witches guild" (or whatever it was called). The lie detector wouldn't pick it up as a lie since he said SORRY and the he doesn't want to die, so he was telling the truth. Also he then killed three innocent people in the top 10 which brings him closer to his goal. ┑( ̄Д  ̄)┍
It’s ok, I didn’t really get the second ship that just came in, in the middle of the chapters lmao
