I think it's great she's keeping him by her side, she shouldn't think about herself since she's the ruler, she should think about the country as a whole, since he's a self righteous man, If she ever loses herself and become corrupt he'll be able to put an end to it by killing her.
She already gained his trust back and it's slowly progressing, from what we've seen from his actions before he's not the type to just rashly kill because he didn't like something, he'll probably ask her about her actions and try to understand her decisions, and before, it took him a lot of time to finally make a move and attempt a rebellion, so if she ever does something again, it'll take more than one incident for him to move, since he's self righteous, he wouldn't overthrow or kill her without definite proof that she's corrupt.
