After their father passed, Joseph eased his brothers’ fears, saying: “Fear not, for am I instead of God? While you meant evil toward me, God meant it for good… Not only was Joseph reassuring his brothers that meting justice to them was not something he planned to do, rather, explains  Ibn Kaspi he was reminding them that as much as a person can plan, it is God alone who decides the outcome.

So too even if he had a nefarious plan to harm them, God could similarly use it to their advantage.
