When Jean first became Dark Phoenix, she murdered the planet of the Brocolli people. An entire planet was murdered. And when Scott was possessed, he was planning on destroying all of humanity. He didn't suceed, unlike Jean and Namor... but that was the plan. In both the case of Jean and Scott, I think it's fair to give them the benefit of the doubt and blame it on Phoenix. But Namor on a given day can flood the surface world completely on his own so it's difficult to say where Namor ends and the Phoenix starts. Difficult to the point where I'm not sure he can fairly be held accountable simply because we'll never know for sure.
But I think at the end of the day, marvel wasn't planning on making Namor a villain so in all likelihood that was more Phoenix than Namor. If the idea was to turn him into an actual villain I'd agree with you... but as the plan seems to have him still be a hero afterwards, I'm doubtful the idea was that was all Namor. Again, just my interpretation.
And yes, Namor surrendering himself to justice would have been the right thing to do. Though I suspect if Namor was going to surrender himself it would be to Steve rather than T'Challa simply because he likely wouldn't feel like being executed anytime soon. But as so often happens in the comic book world, things turned out the way they needed to turn out. Namor was needed in the Illuminati since he was the ONLY person willing to actually do what needed to be done. Had Namor taken himself off the board, Wakanda and Atlantis might have been sparred a war but the 616 universe probably would have been destroyed in an incursion. So in the grand scheme of things, things worked out for the best. Comic book characters are lucky that way.
