Time to take my idea and kill off Han, JJ.
Harrison has begging Lucas since Empire Strike Back to be killed off, and imagine the hate the new villain would get for killing off Han Solo? It'd be glorious.
Lupita Whoever is the new Vader would rise to becoming the most hated villain in movie history with one swift action and be King/Queen of my heart. Do it, JJ!
He needs to die in Act 1 and the Villain needs to remain the Villain for the entire Trilogy though, no Darth Maul/Count Dooku/General Grievous/Darth Vader/Darth Sideous crap.
