It’s not just about the fact that black people die.
It’s that all they do is die. They exist just to die and be a stepping stone for other characters development.
Perfect example is in the first game the doctor you kill that’s supposed to be abbys dad is seemingly black. When the story kinda got retconned and they needed to show a human figure for the players to relate with he’s clearly a white guy.
This dude is not black.
