Could Sebastian Shaw possibly have been captured?
It seems like killing him was the only option. If Magneto didn't kill him, what would Professor X have told him to do?
shareAt most they could have put him in some kind of cell which is very confined and surrounded by blades. But, I also don't know if he can cause his mutant reaction, so that might not have worked.
shareAfter what Sebastian Shaw did to Magento and probably a lot of other people? He really deserved to die.
Laugh while you can, Monkey Boy!
