He didn't but he didn't have a problem with it afterwards, now he's cleaning up Fantomex's mess by harboring kid Pooky.Don't forget he didn't have the guts to kill the kid, but it ended up being Fantomex who decided to make Apocalypse into Superman.
It's not regression, this is who he is. You're making him out to be some sort of pacifist now. It's been stated in story that he isn't bonding with Hope because he feels he may have to kill her someday, that day was apparently last WednesdayRegressing the character back to something old is not progression.
I agree with Cap, not so much Spidey though. Spidey has seemed pretty hesitant so far to want to engage and has been voicing his concerns.Don't forget Captain America, Spider-Man, Wolverine and pretty much everyone.
