I think it is a step forward to just start your "evil thing" in game to get the impression of how this evil rp affects you and other players, no matter if you are unfortunately alone and what you are doing (steeling the harvest from the field/ kidnapping a person etc...., you can start from the beginning with "small" crimes, see what happens and learn from experience, same for other players who would like to gain first experience in playing a bad boy).
I don´t know what you are planning (and pls ont tell me, that´s OOC). But maybe it gets its own Roleplay-dynamic after time and makes other players interested in joining your evil thing.
If you plan something bigger like an evil guild or cult, that´s fine. I would really welcome new roleplay ideas in this game, we need some "bad boys" , that ´s really interesting. But it becomes more complicated, ambitious and maybe frustrating because of the results which may not fit with your expectations or of the way this evil thing unfolds. When you create a fighter character he probably starts at lvl 1 and works (well, you work for it) hard to reach lvl 100. Same for the roleplay.
You don´t need that much for evil roleplay (no high end skills, no super power stuff). I ´m playing/would play a bad boy by pure roleplaying it because I ´m too lazy to train the fighting skills, for example. Give the other characters what they´re looking for and they would love to be a part of your evil thing (also "good" characters").
I agree with Jupiter to keep it out from OOC as much as you can. I also think it is rather better to interact more with the Characters IG than with the OOC-Players out of game because it starts with too much OOC-arrangements about how you and others should roleplay that evil thing and how should that evil guild/cult look like. Other players may agree with the arrangement first but than expect something else or play their character different because of unexpected developments. What is more important for achieving in game aims: The character who matches with the vision or the player behind? The practical experience could be different from the theoritcal arrangements, because we are all individuals.
Just start your thing (maybe with a "Test-Char"). You can also roleplay in the forum, writing subtle things and look how other characters react to it in the forum. I´m looking forward to see/read something from you
