HFCS isn't particularly high in fructose. Sucrose is essentially 1:1 fructose to glucose. HFCS is typically either 42% or 55% fructose, the rest glucose, so basically the same. Honey and agave nectar are also similar.

I can't say I'm an expert, but I haven't seen anything where consuming fructose is worse overall than other sugars. Fruits for example also tend to be high in fructose, and if you're going to have sugars they tend to be one of the best ways.
