The correct play?

[Perk]

I'm playing in a 20 man tournament with a bunch of friends and I end up heads up with my friend Aaron for first place. He has roughly 6500 chips to my 6000. He is a maniac who is very unpredictable and makes many, in my opinion, poor calls that he gets lucky with to win. I get dealt JJ. Blinds are 250-500. I call and raise another 500. He comes over the top, raising to 2000. I figure he probably has AQ or AJ so I go all-in. He takes awhile to think about it before calling. He shows KTo. 5 hearts come down on the board and his king was a heart, eliminating me.

I felt I made the right play, but seeing as I lost, I wanted to get the opinion of some other players. Did I make the right move going all-in?
