Highlights that someone resorts to an extreme, often unreasonable, action to achieve a goal. It usually carries a critical or incredulous tone, suggesting the speaker feels the extreme step went too far. てまで attaches to verbs; までして attaches to nouns.

Noun 徹夜 + までして; a noun takes までして.
• Tone: usually critical or expressing disbelief that someone went to such lengths. • てまで takes a verb; までして takes a noun. • Often paired with a negative or 'not worth it' conclusion.
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ~てまで/までして is tested against.
てでも expresses the speaker's own determination ('even if it means...'), while てまで typically criticizes an extreme act as excessive.
ほど describes degree/extent neutrally, whereas てまで frames the extent as an extreme, often unreasonable, means to an end.
