how does te form+ なる(ものか) work?

Question

i pretty much know what it means, but i wanna know the nuance, what the person tries to actually say. what the なる here does??

Answer 1

This なる is fundamentally the same なる as in ～てはならない. For details, see Origin of ~なければ ならない

ものか is a rhetorical question version of ものだ.

• くたばってはならない。
  I must not drop dead.
• くたばってはなるものか。 = くたばってなるものか。
  How should I drop dead?
