Why is the final mass of a star at the moment of core collapse sometimes more important than its initial birth mass?

Answer

Significant mass loss occurs due to intense stellar winds beforehand

Massive stars shed a significant portion of their outer layers before the supernova event. This pre-supernova shedding means the mass present at the moment of collapse dictates the remnant object, not necessarily the star's original mass.
