What others call "self-loathing" I call instead "moral self-discipline". It stops the excuses, the delusions, the self-licensing, and guards against narsasim. I'd take what you call "self-loathing" a hundred times over the slightest risk of ever accidentally becoming like either my wife beating dad or like certain other men we all know about. (My genetic dad: Not My namesake Mr Lombardi who is technically my stepdad and who is a good man.) Letting go of that protection seems as stupid, to me, as not wearing a seatbelt on a motorway. Yes, a crash might be unlikely, But I would not risk it anyway! I'd rather feed myself slowly into a slow-moving rusty wood chipper than become my evil genetic father! So, I am not risking it. I'd rather be unhappy than become a danger to others.
