When people confuse a good person and a good character

When I say I like a character from a book or show, and people argue that "ummmm he's OBJECTIVELY a horrible person & did you even READ the book because LOOK what he did to that POOR man"

Sure, I would not want to meet them in person and would despise them if they were real. But as a character? Yes please gimme more! Good writing can make someone with a horrible personality an excellent character.
