Something that has made little sense in the Mos Eisley cantina scene is why Greedo wanted Han Solo dead
GREEDO: You can tell that to Jabba. He may only take your ship.
HAN: Over my dead body.
GREEDO: That's the idea. I've been looking forward to killing you for a long time.
HAN: Yes, I'll bet you have.
Is there any indication why he wanted Solo dead so badly? Jabba didn't necessarily want Han dead at this point (per the restored original scene where they talk shortly afterward), just captured. Greedo wanting to kill Han seems to be out of something personal.
