Rufus Scrimgeour really isn't given enough credit for what he did, he took over the ministry after Fudge left it in ruin, he was building it back up and was pretty good at it to. He was kind to Harry even though they disagreed on a lot of things and he refused to give up Harry's location to Voldemort even though he knew exactly where he was. One of the best (and personal my favorite) Ministers for Magic
