Senior Fanboy Killer
Interesting thread.
Instead of answering the step questions, let's rush to the big one. Could Frank do it?
Well, yes and no.
The main advantage Frank would have is that once he tangled with a perp, that would be it. The perp would either be dead, or Frank would be dead. Unlike Batman, Frank plays for keeps ....meaning there will be no crazy situation whereby perps escape from arkham asylum, or blackgate prison, like there was some darn veritable revolving door or something!
Thus, every success Frank has is A PERMANENT SUCCESS, which cannot be said about Batman (who although very efficient, operates in a city that is not as efficient at keeping criminals behind bars).
Thus that would be Frank's major advantage.
His downfall would be that unless he takes out the BIG guys first (especially Joker), sooner or later the criminal population would know that there is a killer out there gunning for them. As someone said, Batman had a certain level of respect (particularly from the Joker). If the Big Boys are not taken out, what you will see is a major hit out on Punihser that involves everyone from your local street hoodlum, to the InterGang (who have been used as hitment, and they have Apokoliptan technology), the entire League of Assassins under orders from Ras or Talia, to even specialized assassins like David Cain, Deadshot, Shiva, and DeathStroke (a combo of Deathstroke and Cain against Punisher would be too much for even Batman).
Thus, unless Punisher wipes out the head, he will die once word gets around.
Finally, the upper echelon of criminal in Gotham is very cerebral. There is a reason why Superman couldn't solve Gotham's problems during No Mans Land (the guy completely and utterly failed, and had to fly off with his tail between his legs and leave the job to Batman). That is the thing about Bruce ....he is not just a Shiva without breasts, or an older Nightwing, or David Cain without guns. He is EXTREMELY cerebral (in NML he once said he had a plan, which had 7 back up plans, and 7 back up plans for EACH of those 7 back up plans ...do the math).
People like the Joker appear like clowns, but in reality the Joker And even someone like Enigma) is not a character you would want in your city. It is just that in the cartoon, and in the movies, he is usually portrated as some laughing guy who will make you inhale laughing gas. He is not ....
Frank may have sizeable problems dealing with criminals who operate in the obtuse .....who make no sense, not because they are illogical, but because they are so super-logical they APPEAR insane (in truth, Enigma and Joker are anything BUT insane .....think of Batman after having one too many expressos).
And then there is the Red Hood. Basically a Batman-esque individual with access to all of Batman's toys, and is not afraid to kill.
Gotham is an 'interesting' city (as Superman found out). Taking of of Bludhaven's criminal population is much different from doing the same to Gothams!
Punisher, in my opinion, does a good job. And then suddenly he disappears and is never heard of again ....although people notice that suddenly the Joker starts sporting a rather interesting flesh-colored leather parasol ........and matching boots ......
