The 27-year-old Liverpool striker -- who has been banned for lengthy periods for two previous biting incidents -- is alleged to have bitten Italy defender Giorgio Chiellini in their World Cup Group D game on Tuesday.
Governing body FIFA are investigating the incident and if found guilty of biting he could face a ban of up to 24 matches.
"The formative years of people's development do contribute to their personality. If you look at his history, Suarez had a fairly hard upbringing (he was one of seven children born into poverty), which would have been fighting for survival - he was streetwise," Dr Tom Fawcett from Salford University told the BBC on Wednesday.
"If it's happened before, it'll happen again," Fawcett said. "Despite all the help, he's going to do it again."

Fawcett said that Suarez required more help than just spending some time undergoing therapy with people such as him as the problem was so deeply etched in his psyche.
"I would suggest he is hard-wired in this way," said Fawcett. "It's not something that's going to come out of his character with a few sessions with a psychologist.
Fawcett didn't offer up much hope that this problem would be resolved any time soon.
"It's in the man. I would think that in five years' time, if there was a certain nerve hit or chord rung with Suarez in a different situation, he would react in the same way."
Suarez, who had shown his better side when he scored twice in the 2-1 win over England last week just a month after undergoing knee surgery, had shrugged off the incident when he spoke to Uruguayan TV after the game.
Fawcett added that Suarez's temperament could not cope with high octane encounters where there was a lot at stake.
"He's a talented footballer but very vulnerable in intense situations, and Italy versus Uruguay was always going to be hot-tempered," said Fawcett.
The Uruguayan Football Association has until 2000 GMT on Wednesday to respond to the bite allegations.
