Katherine
Then you compromise everyone else. Explosives kill people Katherine. In case you did not know. They Explode, and do not care who is around them when they do. Sometimes they explode when you do not what them to, sometimes late sometimes very early when they're being placed.
And when they explode? There is little left to identify the person or persons by.
If people I care about die because of you, you will not have to worry about Him killing you. And your Elf will not be able to save you.
