Is "would" appropriate in this case?

"If these same situations would be held by people unable to change their behaviour in order to solve or to handle them the consequences would be catastrophic."

I know that usually the word "would" is not accepted in the protasis of the third conditional, but is there any possibility that this sentence is actually correct?

Solution 1:

I'm not a professional at this, but here's my opinion. I think the word "would" is correct, but I think there would be a comma after "handle them":

"If these same situations would be held by people unable to change their behavior in order to solve or to handle them[,] the consequences would be catastrophic."
