An assassin

Just because all love in this world was fated to fall apart doesn't mean that there's no jealousy, or other such charged emotions. If anything the world has more of that. For vengeance, for dignity, or just some good old fashion crab bucket mentality, some want others gone in all the sense of the word.

So abundant and intense were these emotions that there's a lively market for assassins. For , preemptive strikes, whatever. You don't care so long as you get paid. It's not the most conventional of jobs but it's certainly exciting if nothing else.
