They'd probably only kill the predator as a last resort, attempting to subdue it, but the predator would honestly be completely outmatched by star trek technology. Phasers would easily dispatch one, the only real difficult part would be the cloaking, but as predator cloaking seems less efficient that most cloaking, they could probably just detect it anyway.
Predator reminds me of the oh I forget the name of them but they were the minions of the Dominion, only less advanced.
Having said this, I'd love to see a klingon fight a predator.
