I wouldn't personally key his car, but if someone else did I would just say "oh well, he had to know he had that coming."

And if someone was in the far corner of a half empty lot, that kind of blatant "look at me, I'm a douchebag who thinks my car deserves more spaces than yours" park job would still solidify his status as an asshat.
