Why are you surprised? To mutants, the Inhumans are the bad guys in this story. The reverse can be said if you read the Inhumans books (albeit to a lesser extent, because the threat Inhumans pose to mutants--the continuation of the T-cloud--is great and imminent, but the threat mutants pose against Inhumans--the destruction of the T-cloud--is not an active situation yet,). This is a more complex story than it's being given credit for, even if it is still not a particularly good or well written one, IMO.
Plus, the Inhumans aren't superheroes (or villains, or anti-heroes). That's not their thing. They're flawed. They don't always make the right calls, and they aren't obligated to rectify things. They've never been portrayed that way. Thinking of them as a superhero team doesn't do justice to their side of things, honestly.

As far as guilt or blame goes, I feel like it all comes down to intent.
Black Bolt detonated the T-bomb with the intention of stopping Thanos from destroying Attilan, killing all Inhumans, and then cause further on Earth (to humans and mutants alike). That's noble and understandable, right? He sacrificed his empire, lost the throne, destroyed virtually the entire supply of Terrigen, and risked the life of himself and his people to stop the Mad Titan.
Black Bolt didn't intend on any of the adverse affects to occur. He didn't intend on the terrigen not adapting to the planet's atmospher. He didn't intend on the mist bonding, creating a pair of roaming cloud that would traverse the planet for years. He didn't intend on that cloud to devastate the mutant population. He didn't intend on hidden human-Inhuman hybrids on Earth having weak genes that couldn't survive terrigenesis. He didn't intend on anything (including, I'd argue, the mists affecting virtually ANYONE on Earth at all in either a positive or negative way, since mutants reaction to terrigen has been reconned a thousand times and NuHumans weren't even known to exist or be widespread at the time--although that last point is debatable, but since Black Bolt can't speak for himself, we don't truly know what his overarching plan may have been). How could Black Bolt have possibly predicted this domino effect coming out of one reasonably good decision that was hastily made in a time of panic, stress, and crisis??
My point is, Blackagar made a last-minute decision working with the best information and plan of attack he had to deal with an imminent threat, which was Thanos. If he wouldn't have detonated the T-bomb, then Thanos could have killed even more mutants (all of them, potentially) than the T-cloud has. The fact that his action were also defensive of both humans and mutants has to factor in somewhere right?
And also, I feel like someone needs to address how Inhumans have reacted to this complicated situation. So far, they have:
- Put some of their most intelligent minds (Iso) on the case to help mutants/Inhuman interests by rectifying the bomb. (
Uncanny Inhumans #1)
- Allowed mutants (Beast, Frenz) access to their superior tech and labs to find an M-pox cure or try to salvage the terrigen within the cloud somehow. (
Uncanny Inhumans #1)
- Actively search for and rescue mutant refugees who were in the path of the T-cloud. (
All-New Inhumans #11)
- Personally given medical treatment and refuge to mutants (Hellion, others) who were already affected by the T-cloud. (
Uncanny Avengers #6 /
All-New Inhumans #11).
- Be scolded by mutants (
All-New Inhumans #11).
- Be told-off by Inhumans (
Uncanny Avengers #6).
- Seen Black Bolt step down as King, at Medusa's insistence, as a direct result/consequence/cause of his actions by detonating the T-bomb.(
Inhuman #12)
- Seen Black Bolt and Medusa brawl and then separate over the events that followed the T-bomb. (
Inhuman #2)
- The Royal family dealing with every other non-mutant related situations happening in their massive world of millions of Inhumans and NuHumans. (
in like every single issue of every Inhumans book).
I'm not saying the Royals or Black Bolt (or Maximus even) are completely innocent and shouldn't be criticized. The Royals have definitely not been as outwardly compassionate and understanding as they should've been... But it's not like the Inhumans are ignoring or not sympathizing with mutants. They have been shown doing just about everything in their power to help mutants----except one thing: destroy the cloud, which would effectively end Inhuman society forever (and as Royals, it should come as no surprise that they're unwilling to jeopardize their own people over ANY others; regardless of the morals and regardless of the fact that the X-Men would likely lay down and die for the safety of most Inhumans if they were given the choice. Contrary to recent belief: the Inhumans and mutants aren't the same)!
I don't get why it's so hard to see the Inhumans characters' point of view in this... the mutant reaction, IMO, is justified just as much as the Inhumans' own. Mutants are being forced to take up arms now, because it's all they can do at this point. If the situation were reversed, I think Inhumans would do the same--regardless of the fact that mutants might not (which is conjecture, but whatever).
Lastly, I'm not playing teams at this just because I consider myself an Inhumans fan. I'm also an X-fan and I happen to read BOTH franchises' books, and I'm getting the complete story. I could just as easily say some of you guys are only on the defensive because of bias against Inhumans and for mutants too, couldn't I? But I don't, because that doesn't add anything to strengthen either "side"'s argument or debate.
