That's the point, though, because at the end you realize that he wasn't the villain, but just a common thug who happened to be in the right place at the right time, and who for some reason was selected by some unknown person in the future. The real villain (if there is one) is yet unrevealed. Whether you think that's cool or ridiculous is up to you.
This is a movie that needs to be seen more than once, and that needs a sequel in order to be complete. I kind of like that and am kind of frustrated by that, depending on the day.
