And yes you can argue the greater good was stopping Thanos (though that's debatale since Thanos and the Cabal were frankly doing more to deal with the incursions than the heroes by this point). But T'Challa's revenge scheme onlly put that plan in jeopardy. Again, he put his own agenda ahead of the greater good and it ended up a fail on his part. But to his credit, he learned from that and didn't make the same mistake later. Again, the point being T'Challa and Namor were able to actually act like heroes and work together for the greater good rather than spending their time trying to kill each other. It's heroes actually acting like heroes, which is exactly what was needed.
If for whatever reason they wanted to kill each other, they can save it for AFTER the multiverse is saved. Though the fact that they both saw the wisdom in ending the conflict rather than continuing to kill each other works too.
