If Saddam Hussein had not been toppled, what do you think would have happened to Iraq during the Arab Spring?

If Saddam Hussein was still in power in Iraq during the Arab Spring, what would the consequences have been? Many people critizise the invasion of Iraq for destabilising the Middle East and destroying Iraq, but if Saddam hadn't been toppled wouldn't it be possible that we would have a situation similar to that of Syria, or even worse, considering his history of brutal repressions?

Curious to hear what you guys have to say, since this is something I have been thinking about a long time.
