Having read the first thread now and having had a moment to wipe the blood from my eyeballs, I'll drop a few things here that may be of help for Magitex and/or any others who wish to play baddies. I hope this helps.
Continuity checking:
Try checking to see if everything leading up to the action in question is supported ICly. All character knowledge must stem purely from IC sources and events. All actions must be things that are natural and possible in the IC world. ( Spawning somewhere / logging in is not natural icly. Likewise, graphical glitches and game exploits are not natural in the ic world ) .
IC/OOC Separation:
You absolutely must keep all *player knowledge* out of your character's heads. Never let your character act on information that is in YOUR head, but not in HIS. Your character only knows what he or she experiences in the IC world. Your character knows what they have seen, heard, tasted, touched, and physically felt. They do not *just* know things because its convenient for their player.
If you catch yourself saying "my character WOULD HAVE or COULD HAVE or SHOULD HAVE known X", then you are probably cheating. Your character knows only what enters them through the five senses. Uf you make an exception for some magical ability like azure way, then be clear about it with fellow players and make sure they are ok with it.
*** Keep in mind here, players who do not yet know how to separate their character's mind from their own mind will not be able to do this. Unless you want to get into a tiresome argument, do your best to avoid situations where the other player needs to be able to do this. Don't tell unskilled players IC secrets in OOC chat. Only do that with solid role players if you feel there is some need to do so.
NPC Acknowledgment:
Play as if the NPCs are regular citizens. Play as if the Guards are real and are watching. Assume that *good* characters will respond to requests from guards. For bad characters like ( ie. Zak, Guile, Reliom ) you can generally assume that they will follow self serving or malicious motivations, but ultimately, you as a player cannot really make assumptions about what an NPC *would* do or say. That right there is pretty close to god modding the NPC.
Assuming that a Guard will not notice your actions is just as bad as assuming that an NPC would readily rat you out to the guards. Its best to avoid this kind of situation alltogether when possible. This means, do not role play crimes in front of other NPCs and do not try to play the "NPCX would have said this" card.
Play Realistically
This ties in with consistency checking. Just because your character can stuff 30 swords, four large, oak cabinets and a few berries into their sack does not mean that they can do this ICly. You need to think critically about your character's abilities and limitations.
Personally, I make my characters forget things, drop things, or just flat out screw up. These imperfections in play will give other players good opportunities to get a foothold on the action.
Did you hear the story about the unknown thief who never got caught?
Yah, neither did I. In role playing and in story writing, this does not work out so well. A role played thief who never gets caught and is completely unknown looks nothing like a thief. Unless their thievery comes into play in some other way, they might as well not be thieves in the first place. If you are going to play a shady character, then make sure and get hem a little dirty. They don't have to be the town misfit, but they should not be squeaky clean either.
Getting Caught and Consequences
If you are going to play a criminal character, then really get into the character and play all the consequences too. Makes mistakes here and there, let other characters accuse you and try to prove them wrong. Allow other characters to chase you and try to throw them off your trail. When you eventually get caught, play your consequences! Role play your time in the cell and if you do it well enough, you'll have fellow players sending their characters in to visit (or taunt ) your character.
