A big lesson from Trump and others like him is that when someone’s a piece of shit and brags about it in public, it looks innocuous and at best it may be revealing and may validate your views on power and the flaws of society, but on another level he’s likely to give voice to, rally and convince other assholes to feel entitled and protected to act like assholes and then you have an actual problem. So yes, polite amorality is better.
