Yes, I would consider that the new player wants to make a character based around the assasination of the Rules Lawyer character, as a bit of a red flag.
FIrst of all, do you have any particular Player vs Player rules with the group as far? My experience, unless yours is the rare mature group that can embrace that aspect of role-playing and story telling, it is usually a fairly standard houserule that players must make characters that will not resort to PvP actions. Most people coming to a table for a D&D-esque game won't even be considering facing their party members as opponents and can be quite shocked and hurt when their avatar in the game is suddenly backstabbed by someone else at the table. There is also the flip side, which certainly applies in this case, that PvP aggressive actions are based off meta-game reasons, and turn into full-out warfare. If the Story-heavy player dislikes the Rules Lawyer's play style and makes an assassin for the current player's character as a way to 'get back' at this player, after that character is dead, what next? Is it going to be an endless stream of deaths for the Rules Lawyer's characters because the real dispute is based on Out of Character concerns? An attempt to frustrate them and get them to leave the group?
The reconciliation of this will depend largely on you, the play-style you want to have, and how close you are to players as friends. However, I highly reccomend that you use Out of Game conversation to reconcile this, and would definately try to get it resolved so PvP is not a thing. Some things to keep in mind.
-Are you already friends with the Rules Laywer player? Will the rest of the group see you as a dick if you bring in this new player that is annoyed and disagrees with the current playstyle of one of the established players? How much of a factor is Loyalty to the old group and current way the game is being played? If everyone is currently having fun, is it worth changing or allowing something you wouldn't normally (PvP) to bring in a new player, or should they look for a different game that better fits their playstyle?
-Is there a particular playstyle you wish to cultivate in your games? Can you sit down with one player to discuss how they might change their playstyle to be more friendly to a larger group (either regarding toning down the Rules Lawyering, or toning down/removing PvP motivations). Could you remove players of an undesirable play style from the group without repercusions (hurt feelings, lost friendships, etc)?
Really, hate to say it, but unless I was in your shoes, I don't know exactly how to handle it persay. In general though, my personal thoughts:
-The group that you are having fun playing with deserves loyalty and preservation before trying to change it up to accomodate a new player, especially if that new player is asking for a change that could very easily tamper with the fun currently being had by the original group.
-PvP rarely ends well unless you have a group dedicated to the overall story, and in general, I do try to heavily discourage it. A player who has outright stated that their characters goal will be the murder of a PC from the outset, red flag, I would not be inviting them back.
