Stronger

What doesn't kill, will make you stronger. This statement is false with only 3 exceptions. Either A, you completely lucked out. This option can however be ignored as it's as good as impossible to occur naturally.

Option B, you happen to be a protagonist and it's inevitable for you to climb to a higher level of power.

And finally, option C, the near death experience was carefully crafted to ensure benefits. An example would be taking a carefully prepared cocktail of venoms to develop venom resistance.
