Is it possible to start a sentence with "worse than"? [closed]

Solution 1:

Worse than those who do something are those who do something else.

Syntactically, this an example of subject-dependent inversion, where the adjectival predicative complement "worse than those who do something" is inverted with the subject "those who do something else".

This type of inversion puts the subject in final position, where it typically receives greater phonological prominence than in its basic position.
