So the entire purpose, which cost the lives of everyone, was of Keyser Soze wanting to kill the only man who can put his name and his face together, but at the end the cop knows who Keyser Soze is and would have plenty of mug shots and fingerprints of him.

Yeah but even if your take here is true, he still got away with it and can now go and disguise himself and hide out in a non extradition country forever.

And actually, I'm pretty sure that his motivation wasn't to kill the only person who could identify him but to actually get revenge on EVERYONE who had stolen from him or ripped him off or did him wrong at one time.

Remember the pool table scene when Kumbayashi tells them all that they have wronged Soze in some way and didn't even know it at the time. If that's the case, then your whole premise is off bc that was not his actual motivation. In fact I think that was what Chazz thought that Keaton's motivation was, but we know Chazz's whole theory on Keaton and everything about Keaton's motives, such as that one, was wrong.

In addition, Chazz was only suspicious at the end. He was not one hundred percent sure that Kint was Soze. You could tell by his confused reaction. He was so convinced it was Keaton and Spacey was a nobody, he needed more than new evidence to turn him in an instant. Not that this matters to your so called plot hole, but in case you argued that Chazz would send out people to find him asap. In which case he still was in Kubayashi's tinted window car so he still would've gotten out by then.

It's not a plot hole because the story is about Soze risking a lot and going to great lengths to pull off an almost impossible hit without being identified but he failed on account of someone else living to id him in the end. He thought that he got away with it. He didn't know that the guy lived while he was being interrogated by Chazz. I still think that The Usual Suspects is one of the greatest stories ever directed.
