But NRL veteran Marshall wondered why Folau was not given another chance, claiming players had done worse in the past and been accepted back by the game.
“It doesn’t faze me if he’s allowed or he’s not allowed to play,” Marshall told NRL 360.
“I definitely don’t agree with the things he’s said, but to me, I think we need to decide what we forgive and what we forget.
“Because, and this is my personal opinion, I see domestic violence as worse than what Israel did.
“I don’t agree with that, and yet we let people who have done those actions come back into our game [in the past].
“So where do we sit now with what’s right and what’s wrong?”
Marshall conceded the ARLC had made great strides this year with the introduction of the no-fault stand-down policy following an off-season from hell.
But he still questioned the NRL’s consistency over Folau’s treatment after the likes of Matt Lodge were thrown lifelines.
Lodge was deregistered after a 2015 New York attack but cleared to play for Brisbane last year and is now being considered for the 2020 Broncos captaincy.
However, St George Illawarra forward James Graham claimed the Folau and Lodge cases were very different.
“The guy [Lodge] has apologised and gone through a process to get back into the game,” he said.
