Zorg really isn't even the antagonist. The "absolute evil" is. Dallas isn't really the protagonist, that's the Priest. Dallas and Zorg are set pieces getting moved around. The unsuspecting hero and the messenger.
If Zorg hadn't had Leeloo's ship blown up, she never would have tried to escape and fall into Dallas's cab. A lot of good/bad luck scenarios. Like having one match left at the end.
Mr. Kim : You got a message.
Korben Dallas : Yeah
Mr. Kim : You're not gonna open it? It might be important.
Korben Dallas : Yeah, like the last two I got were important. The first one was from my wife, telling me she was leaving. The second was from my lawyer, telling me he was leaving... with my wife.
Mr. Kim : Ah, that's bad luck. Grandfather say it not rain everyday. This is good news, guaranteed. I bet your lunch.
Korben Dallas : Okay, you're on.
Mr. Kim : Come on...

Mr. Kim : You are fired. Oh.
Korben Dallas : Well, at least I won lunch.
Mr. Kim : Good philosophy, see good in bad, I like.
