Yes, unfortunately, I agree with the attorneys you spoke to. This does amount to name-calling and would be unlikely to be considered defamation. In order to prove defamation, you would need a false statement of FACT.
This means a false allegation that someone has done something that they didn't do. If someone were called a child molester for instance, that would allege that he or she had molested children. Since that would be untrue, that would give rise to a cause of action for defamation.
However, calling someone a corpse, or the most shameful in the world, do not constitute false statements of fact and would be considered just name-calling.
That said, you still may be able to have this content removed by sending a 'cease and desist' letter to the website, stating that you will sue for defamation if the content is not removed. They may be worried enough about a law suit that they will take down the content voluntarily to comply with your cease and desist letter.
