Anthony Joshua doubled down on his controversial “kill” comments to Jake Paul after being challenged on the comments at a news conference in Miami on Wednesday.
The remarks were first made on Tuesday when Joshua was asked whether he would hold back against Paul, with Joshua saying “if I can kill you, I’ll kill”.
Saturday’s fight against YouTuber-turned-boxer Paul has attracted criticism over safety concerns and the size difference between the fighters.
And former world heavyweight champion Tyson Fury called Joshua a “classless loser” for the “kill” comments.
But Joshua, 36, said: “It’s my job, we fight. We have a licence to kill.
“I’m sure many people don’t understand it but this is what my job is. I just enjoy what I do.
“Whatever happens, happens – as long as my hand is raised, that’s what’s important, respectfully.
“That’s just what the mentality we have to have as fighters. I don’t know if other fighters think that way. Maybe they’re a bit more tame.
“The way my mind works. When you’re in the ring, it’s a dangerous thing. Anything can happen.
“You hope your opponent leaves the ring safely, but if they don’t, you still have to go to bed knowing you just did your job. It wasn’t personal.”
Paul, who is a huge underdog in the heavyweight contest as a natural cruiserweight, was no less incendiary in response.
“This is a modern day gladiator sport,” Paul said.
“I’m ready. I want his hardest punches. I want there to be no excuses when it’s all said and done. Let’s kill each other.”
