Combo - A real good guy.
I've seen a lot of people saying "Combo didn't deserve that ending even though he did what did.". Ok, Combdo did kick the *beep* out of Milky but it wasn't out or racism. Combo, like the majority of the characters, comes from a broken home, he was a frustrated guy. Of course this doesn't make what he did right, but understandable to some point. Also, I remember from the movie, in the scene where Banjo and Combo scare everyone right after coming out of jail, Woody says that Combo actually went for jail to protect Woody. In 86, when he reappears, what does he do? Protects Lol from going to jail by pretending he was the one that killed her father. Let's not forget that in this time 86-90, we don't see Lol nor Woody ( the one he saved, and the lover of the person he saved) visiting him at anytime, how *beep* is that? So, what do know about Combo?. He was a kid from a broken home with a lot of anger in him that made some bad decisions (which he regreted right away since we see him crying and taking Milky to the hospital right after he attacked him) but did time for two of his friends, something only a real altruist person would do.
On the other hand, we have Milky. A guy who *beep* his best friend's girlfriend and actually made her pregnant. Not only that, but a guy who hired hitmen to kill someone who BEAT him, but not kileld him, that's not justice. And how big of a *beep* do you have to be to send a guy to his death like that even after a sincere apologize at that coffe shop. Oh, and let's not forget Milky's background, a healthy, functional family for what we can see, way different of Combo's.
Basically, Combo was a good guy, although unstable, and Milky was a backstabbing coward.
