Yup, you are given a choice to kill the token black character, or the bitch ass white boy who has a change of heart randomly (spoiler: i killed the white boy)
Neither choice really makes sense and it feels like this was added last minute. Once you make the choice, the other dies and... everyone just kind of ignores it and you're immediately thrust into more shit and fight the final boss (with another random death thrown in for good measure) and you get your cliffhanger cutscene and wait for Gears 6 I guess
