As long as you keep your fructose intake relatively decent, there is really no need to worry. Calories in & Calories out still applies.
It'd be quite hard to actually ingest harmful amounts of fructose through just fruit, that's a lot of fruit to eat.
edit: and even if you did manage to eat so much fruit you would need to do so consistently to run into problems.
