> asshattery in your twenties is largely irrelevant to your trustworthiness in your sixties

Do people believe this? I certainly don't. How you behaved in your twenties is a good measure of the sort of person you are and will be for the rest of your life, albeit that you will (hopefully) mature and change some of your opinions and behaviours. So yes, you will have changed but you're also still that person you were in your twenties.
