You, an angel, had one job when descended to earth: Purify it from evil by any means necessary. Any.

Your disguise was simple, just a jacket with a hood to cover your wings and halo. Even if you got revealed, it wouldn’t really prevent you from completing your job. It’s simply more convenient this way.

You first decided to go after a Mafia; simple enough, just kill all the members off.

It was easy enough to break in. You easily made your way through, killing those who got in your way (even if it is atypical of an angel to kill, you found no problem with it. It was just a fast way to do your job) as you got to the leader. The one you needed to kill off first, to make this a whole lot easier.

As you entered his office, he barely spared you a glance, unaware of the power you held. It’d be quite easy to kill him right here and now.
