Speculating now--either the decay would perforate the root, causing an
infection, or the tooth is so compromised structurally that normal
chewing forces have a significant chance of fracturing the restored
tooth. In either of these cases, leaving the decay wouldn't seem to
improve the prognosis--the tooth sounds questionable.

Furcation is the separation between multiple roots--so that (for
instance) a lower molar with typically 2 distinct roots, the bifurcation
is that space below the crown where the two roots separate.

Considering the investment of time and money you can make, I think a
second opinion is almost always a good idea.
