How could Urouge beat cracker and enraged army when he just defeated Snack? Did you see what happened when Luffy beat cracker? He couldnt even survived Sanji attacks or enraged army.
Capone is the one who made the assassination plans, capone saved the alliance some time with big Father, Chiffon contributed in the cake baking! The only thing Luffy and crew did more was Luffy beating Cracker and katakuri.
Kidd isnt there fail, stop writing stuff as if Zoro didnt fail in NW many times. He recently failed to even round up samurais.
Luffy hinstl also failed many times, neede help from Capone/germa/fishmen , help from law to take down Doffy family.
