Shooting first sure did lead to a lot of trouble.
All those nameless monsters and NPCs who the heroes kill in their adventuring careers - they have families. Sons and daughters, many who would love to get some sort of revenge. You barely even need to justify this sort of story development in a game.
Commentary by memnarch (who has not seen the movie)
Ahahahahaha! Sure, it was only in the last comic, but having a guess confirmed like this is so great! Greedo is totally Kylo's father! And this handily explains how Kylo's got Force Powers as well, at least in the comic. This would be yet another way Qui-Gon messed everything up, wouldn't it? It's years late at this point, but that's finally coming back around to biting Jim in the butt personally. Once Kylo does end up throwing Mr. Noname off the catwalk, I hope someone else is going to point that out.
Movie guessing? I got nothing. Maybe Han and Kylo actually know each other somehow beyond the "important leader of the other side"? They're practically an arm's length away in these panels. Han never seemed as stupid as Jim's character was, so there's something fishy going on. Besides the red lighting anyway; it's not helping Kylo's complexion in the slightest. It almost feels vampire- or zombie-like in coloration, especially in that last panel.
Transcript
Kylo Ren: During the scuffle, Anakin and I got scraped and grazed. Blood from his wounds smeared onto mine.
Kylo Ren: I didn’t realise at the time, but his midi-chlorians entered my bloodstream.
Kylo Ren: When my father discovered I was still alive, he kept it secret, letting everyone believe I was dead.
Kylo Ren: He sought a job on a freighter, taking me with him. He worked his way up, until he could afford his own ship.
Kylo Ren: And that’s when he ran into you. He was looking for a job to pay back an old debt to Jabba the Hutt.
{flashback scenes of Han Solo meeting Greedo in the cantina on Tatooine}
Han Solo: {the sepia-green alien} Oota goota, Solo?
Greedo: Scusi, mia no speak space-Italiano.
Han Solo: <sigh> I said: The name’s Solo, Han Solo. Captain of the Millennium Falcon.
[SFX]: Pow!
{end flashback}
Kylo Ren: You murdered him! You stole his name and his ship!
(No Name): And his debt! Jabba almost had me killed. So it was your father’s fault!
Kylo Ren: Don’t think you can out-righteous-revenge me!!
