Could you hate what a man did and not hate the man?

“For a long time I used to think this a silly, straw-splitting distinction: how could you hate what a man did and not hate the man? But years later it occurred to me that there was one man to whom I had been doing this all my life—namely myself. However much I might dislike my own cowardice or conceit or greed, I went on loving myself. . . . Just because I loved myself, I was sorry to find that I was the sort of man who did those things.”
~C. S. Lewis
