Fail.

[spockodile]

There was once a vampire who developed a moral philosophy which disallowed acting on vampire instincts. She vowed never to kill or attack anyone ever again. And she didn't.

For a little while.

I grabbed hold my enemy's neck and choked 'till he ceased.
Blistered with disbelief, I awoke dead.

And when I awoke, I couldn't believe it was me.
All the time, it was me.
