Usually it takes a lot for people to lose total respect for each other, but sometimes there's just a single instance that gets under your skin and makes them irredeemable in your eyes. This could be a person you know personally, or a celebrity. Just something someone did that totally killed your perception of them.
One example from me is when I found out about Woody Allen marrying his adoptive daughter. He's a really talented guy and I admired him, but this just ruined him for me. Mind you this is without knowing about the sexual assault allegations by his other daughter, but just the knowledge that he actually raised a girl and then got into a relationship with her creeps me the fuck out. I don't care what says or does from now on, I can't really respect him.
