Honestly, after the week we've had, these kinds of people are who I want to hear about. They learned, regretted, and became better. They give me hope.
There's a chance that some of this is not as genuine as it seems, sure—Riddle mentions his job prospects here, and one could make an argument for the publicity of doing this. But I've had enough negativity for a while, and I'd like to believe it's honest.
