I haven't been following the X-Men, so the Cyclops in Avengers VS X-Men was a surprise to me. The Scott Summers I read as a kid was more Superman/Captain America in his attitude, he wouldn't try to start a war with half of the world's Superheroes just to protect someone that doesn't really need to be protected (The Avengers weren't really planning on killing Hope Summers at first, weren't they?).

What happened? What caused Wolverine to be less of a dick than Cyclops?
