[Rolando]

The adventure will be very different depending on the reach of the murderers.
If the murderer are average Joes they may only reach common people like protitutes/pimps, lazy drug dealers, etc. But if they have some way of reaching for higher profile, less common people you may have some more interesting victims.

Lust: a very rich and corrupt politician pedophile or someone involved in people trafficking.
Greed: someone involved in investment that is involved in market manipulation and other business shady dealing, specially if they are not owners or industrialists, but business actions dealers, so money for more money.
Anger: a military general or someone that sponsors a hate movement.
Envy: the loser of some political election, specially if they are involved in dirty politics and media campaigns to discredit honest politicians (if there are still some of those).
Glutony: a magnate of some food chain, the grossier the food the better, cheap and abundant food that make someone powerful by sickening the population.
Laziness: a very rich person that have a lot of people to deal with their every wish and need, maybe a movie star or the wife/sond7daughter of a powerful politician (the initial target may seems to be the politician for greed, anger, pride, but is the politician dependent).
Pride: a renowned scientist, someone that believe that is above God or act like a God by doing something the murderer think its against God laws.
