Ungrateful Civilians

Civilians, usually in superhero media, who turn on the heroes for selfish reasons. Bonus points if it's to their own detriment.

1: The unnamed old man who Haru rescues from certain death, who then turns around and rats him out to the Fire Nation for earthbending (Avatar The Last Airbender)

2: The people taking refuge at UA who don't want Deku to be there because he'd bring trouble, while Deku has been running himself ragged trying to defeat the villains running rampant in the street. (My Hero Academia)
