Is that Doctor nice? Who give a shit. The only thing that matters is if they're competent. O.J was perceived as the nicest person in the world...

Also, trust your instincts. Who gives a fuck if you appear to be mean. A woman getting on an elevator, the door opens and there's this shady looking man in there. She gets a bad feeling but doesn't wanna seem rude (thanks to society promoting niceness) so she gets on and ends up murdered, for example.
