Marvel has killed so many of our favorite mutants. But, do you think they always killed them at the appropriate time. Pick a currently or formerly deceased (I had to laugh as I typed that) mutant and explain WHEN they SHOULD have died and why.
Cyclops should've died at the end of "AvX." I felt like this would have saved us all those years of shitty stories, unjustified Cyclops hate and this would've been a more fitting end to "Avengers Vs. X-Men." If he had died then, he could've been reunited with Jean in The White Hot Room. I'm assuming as he WAS a host of the FULL power of The Phoenix he would be granted admission to The White Hot Room. This could possibly give us some beautiful one shots of the Scott and Jean reunited and should Marvel want to bring him back there's always the connection the The Phoenix.
