Who is the Reaper?

Some would give comfort,
Others, just death;
Which one will sort
Through those lacking in breath?

Choose your answers,
Name the names,
Be a winner,
Don't shift blame.

1
His roles conflict, the needs cut deep,
But surgeons have no time for sleep,
And even in your final rest,
This saint will strive to serve you best.

2
This nurse, she seeks to do you ill,
Injects your death with proper skill
As, bedside smile upon her face,
She works to end the human race.

3
Born a plague that like man walks,
Comes too close, and ceaseless talks.
He's tiny lives that can't stay dead,
And so he lets you die instead.

4
Killing sister
Casts a spell,
Seeking power,
Making hell.

5
As pretty face to make men pause,
The perfect lady brooks no flaws;
She lends her voice and eyes to charm,
And lifts no hands to dole out harm.

6
Burnt, discarded, and cast out like dirt,
Her name tells a story, and the story did hurt.
But hardy and stubborn, refusing to bend,
Her name says her story ain't ready to end.

7
This hunter of things that go bump in the night,
For price of just money and maybe a bite,
"He" works as a monster from sanity turned,
And laughs winning bounties "she" couldn't have earned.

8
Sharp as her blades, and blunt like her bombs,
Never been taken for "soft", "sweet", or "lady",
But now amidst death, she is practically "mom",
Having found herself stuck with a little tar-baby.
