What do you mean actually fought, didn't they fight lol...also what do you mean killed Hawkins...that's literally Hawkins power, if zoro couldn't defeat all 10 lifes then zoro is in no way neg diff him
Also oda has clearly shown that fight don't go the way people power scale
Zoro was on defensive approach literally using bottom barrel of his attacks and Hawkins still loosing his lives left and right.
Oda showed us that stronger attacks can take out multiple lives, LS kick took out 3 lives while laser just took out 1 life.
Casual flying nameless slash form Zoro took out one life meaning ISDS which is like (low balling) 1000s of times stronger would one shot him
