I think virat is shown as a guy who ignores what is not seen in front of him
I think if sai is with him virat will be satisfied .So even if Paakhi does some unsavoury things he will ignore it .(like a typical male to avoid confrontations)
But in the absence of sai that virat will be dangerous.he will be moody and he won't be feeling a sense of completeness which one get from the nearness of one's spouse.
So that moody dissatisfied virat may think some more vile things are cooking up beyond his vision.so that virat without sai is more dangerous to Paakhi and CM monkeys.
Hope I didn't made a khichedi with my explanation

No yaar,you have stated the most factful point here. Sai brings out Vurat's best and worth. And the biggest truth of Virat is, he and his emotions are a highly deadly combination, they have a destructive potential in them,which he keeps inside or tries to calm them.
