From the perspective of society as a whole, the most important thing is whether or not this drug works. There are limited doses, it has potential to save many lives, but we need good data on it. That means we can't just take the handful of doses and use them willy-nilly, the patients need to be brought to a lab for observation (and to see what happens if given the best medical care available).
Given that the research for the drugs is happening in the US and the US's CDC is really responsible for all of it, that means the patients need to come to the US.
Given that there is not a snowballs chance in hell of a bringing a non-US citizen to the US when they are known to have Ebola (many didn't even want to let a US citizen back in), it has to be a US citizen.
The 3rd outcome is a result of multiple factors, not some insane racist conspiracy.
