The quote itself sounds like it needed to be split up into parts, rather than kind of a run-on sentence. MBJ's delivery didn't help, but that kinda wording can make anyone stumble.
"Bury me in the ocean with my ancestors who jumped from the ships,'cause they knew death was better than bondage." (general statement, probably got it somewhat wrong) It was meant to be poetic and I get that, but it's too awkward to be poetic. It could've been:
"Bury me in the ocean...with my ancestors. (insert dying gasp) They knew death was better...I know it too." Nothing special. Still in Killmonger's vein. Still gets the point across. Still sympathetic. Just not as awkward, you know what I mean?
