I genuinely find it hard to sympathise with the Inhumans' position.
The Inhumans want the cloud to be left alone so new Inhumans can have super powers. The mutants need the cloud to be dealt with so that they don't die.
I've been trying to equate the two positions but I just can't manage it. I keep coming back to this:
If you have to die so I can have super powers, is it right for me to kill you or, by omission of action, allow you to be killed?
No. It isn't. Therefore the mutants' needs must take precedence.
