I HATE it when a character are described to be cold selfish apathetic and couldn't careless about anyone else, the second someone in danger, you know who saved them first? THAT SUPPOSED SELFISH APATHETIC CHARACTER. And it's not at their middle of their development it's at the start of the story. If they are the cold apathetic character the author want it to be, THAN LET THEM BE APATHETIC. I swear, some authors just wrote cold apathetic and couldn't careless about anyone else just to make their writing look cool. I'm not saying some writers can't write apathetic character, but please, if a character is selfish apathetic, then they are not going to step in because, again they're selfish.
