If Ozy's as bad as you say defending making him a slave, for eternity - because it wasn't enough for Nur to make a slave for life he transformed Ozy into being an immortal to keep a slave for that period, this should be a simple argument.
As expected, as long as a super-villain is a mutant they don't deserve any punishment for their crimes against other mutants. It's incredibly tone deaf to bring up Hitler while letting off the mutant ones, the hypocrisy is astounding. You war willing to defend Apocalypse enslaving someone for eternal life, I didn't start that tangent. And Apocalypse has ben a big part of this Excalubur so his legacy on the title shouldn't be overlooked as though he were a dear friend.As for what is in green?
No one except you has said anything like that. Entertaining another oddball tangent is probably not the best way to discuss an "Excalibur..." preview.
