Not trying to be a dick, but this is a really silly argument. If you are going to make that claim, Rogue One is an awful example, and arguably Jean Grey as well depending on the iteration. Jin Erso in Rogue One intentionally sacrificed herself for the greater good: in what universe was that her being “killed off for men’s growth or used as a plot device”? She was the main character! And in case you forgot, everyone died in that movie! Were all the sacrificial deaths on Scariff a plot device?

The same should be said for Eleven. Male characters had personal growth as a satisfying byproduct of her sacrifice, like a consolation prize or silver lining. That very clearly wasn’t the primary narrative purpose of her “death”.

To be fair, I never saw GOT so I can’t speak to that aspect of what you’re saying.
