They still were on Earth, and humans knew there were mutants around. They could try a bit harder.
Mars is like the next street over by MU standards... I am speaking of another galaxy, maybe another parallel universe where Earth has already been destroyed by Galactus or whatever.
I acknowledged that; I explicitly said "Utopia, but on Krakoa and with Apocalyse, Mr. Sinister, Selene, Exodus, Sebastian Shaw...etc."
And you are ignoring that my comment was about the reaction of the other mutants to these villains' presence on the island... they should be scared, their presence should work as a deterrent for mutants to move there, not as a stimulus to do so...
These guys are massive threats on themselves; they all have their own agendas and any of them could ruin everything... Apocalypse has always wanted mutants to become stronger through war; Mr. Sinister wanted to replace mutants with his own engineered species...etc. Even if by some miracle these have become good guys, the X-Men and allied mutants should be terrified of having them around...
So, if there were a guy who were just like you, you would be okay getting killed? If you had a twin brother, you would be willing to kill yourself because, hey, there is another one of you around...?
They seem to be veering towards presenting all of Humanity as trash who deserves to die...
