1) I love to murder evil people.
2) Anything that is not an evil person.
3) My superiors, in spite of sending me to many locations with evil people, seem to dislike it when I murder evil people.
4) A desire to improve the world through murder, and only ever murder.
5) Only if done in as unlawful a manner as possible.
6) I don't understand the questions, so I'll just blame the schools today.
