Raising with KK, too much???

The first hand of a 1 table tournament (9 player)

from middle position I raise 5 times the BB with pocket KK, everyone had folded to me and after my raise everyone folded, all I did was "steal the blinds".

Normally I raise 3 to 4 times the BB when I'm first to the pot, but I wanted to push it the first hand of a tournament, because sometimes you get crazies that are willing to go all in with very modest hands, thinking it's their best chance to win.

I was hoping to get reraised but it didn't workout. Bad strategy or would you employ it on occasion? My other thought is, possibly everyone would of folded to a raise 3 times the BB anyways, what do you think?
