Chris Eubank Jnr. has vowed to display "no mercy" when he fights Tom Doran on Saturday.
He insists he is unaffected by the fact opponent Nick Blackwell was put into an induced coma when he last fought, in March, and that his father's advice ensured that that incident has made him stronger.
By his own admission, Eubank Snr. lost his killer instinct after the 1991 rematch with Michael Watson that left the latter with near-fatal brain injuries. His 26-year-old son, however, is convinced his own similar experience will have no immediate or lasting effects.
"I'm in there to win, defend myself and attack, and to further my career, so there is no mercy. However cold that may sound, there is no mercy, no easing off," Eubank Jnr. said ahead of his first British middleweight title defence, at London's 02 Arena.
"I have to go in there and be as ferocious as I can. It's the referee's job. It's not for me to have to say I should ease up. I plan to put on exactly the same if not a better performance as last time.
"I've seen the consequences of what can happen when you're unprepared for a fight, or not as prepared as your opponent.
"I can't let anything like that happen to me, I've got too many goals, too much ambition in the sport. We're looking to fight for a world title this year.
"[My dad] has spoken to me about it and he said that's what happened [that he lost his killer instinct]. That was him as his own man and in his own mind. We are two different men. I'm not going to let a situation like what happened in my last fight affect my future performances.
"Something like that might affect some's fighting style and mindset. For me, I've used it to fuel myself even more."
Eubank Jnr. has previously spoken of his desire to give Blackwell the British title he won from him. To do so he would need to win it outright by successfully defending it three times -- therefore delaying his world title ambitions -- but he revealed that is no longer his plan.
"[Blackwell's] actually expressed that he doesn't want the belt, as far as I've heard," he said. "I haven't [spoken to him], not man to man.
"I've tried, and things didn't work out, but I'm sure I'll bump into him at some point and take him to one side and talk then. We're looking to fight for a world title this year, and if not I will defend the British title as many times as possible, but the main goal is to go on and win a world title."
