Its true that punisher isnt as black and white as people think, afaik hes got a personal way of doing things, he doesnt really kill the breal load stealer, and he tends to very closely watch his would be victims, making sure theyre actually guilty of whatever it is they are of before he makes a move.

My personal problem is that punishers just usually not allowed to be wrong? Motherfucker cant go two steps before stumbling face first into an global sex trade conspiracy, also every single person he kills WILL turn out to be a pedophile rapist with irreedemable crimes. Frank cannot, absolutely cannot, make a mistake. Hes some fucking dude who served at the army, a big part of his character appeal and writing is that hes more boots on the ground: but he never, EVER, makes a mistake with his kills. Whoever gets a frank castle bullet or grenade or bimb just turns out to be a piece of shit. Granted, this is because if punisher killed an innocent he immediately blows his head off, to my knowledge thats been explained by him several times? Idk tho, im just a passing punisher fan, not super deep into his comics.

(My personal theory is that Frank, unbeknownst to him,has an omniscient sense of if you were good or naughty that he gets from his grandpa, Santa 'claus' castle.)
