At the end of the day, you can not just go around killing people. If this was allowed, any person could use the excuse and say "Well I'm a hit man" as to why they are going around and killing every person on the island. If you, or anyone else, want to play the role of a "hitman", try to be more creative. Maybe kidnap the person you are hired to kill, take them to a remote location, explain whatever they've done to deserve to be killed, etc. There are plenty of ways you can play out this interaction. The point of being on a roleplay server is so that both sides can have a good time during any interaction. It is not fun for anyone to just be randomly shot out of nowhere without knowing why, on the other hand, although getting kidnapped and/or killed is not always the ideal situation, if someone gives me fun, unique, and interesting roleplay leading up to, I always tend to enjoy it. Hope this helps
