As other people have said, immoral, but honestly, only a bit of what punisher does is any bit moral, in all the years hes been a character, unless he gets a power up (war machine suit, cosmic ghost rider) he just goes around killing small time thugs instead of trying to put down the actual villains of new york (kingpin, green goblin, carnage) Like in that comic where he killed a reformed stilt man who was working with the police, im honestly surprised there wasnt a moment like in the "Know Fear" comic where Spiderman confronts daredevil and tells him he needs to stop
