why didnt Harvey Dent kill the joker?

The joker gave Harvey Dent the gun so why didnt he kill him ??

Because the DCU lack Balls!

And the people of Gotham pray their little hearts out for Punisher to come knockin'

^WTF?

Well, if you mean TDK...remember...Harvey flip his coin.

Joker is one lucky man.

sorry i forgot thanks anyway
