[quote=Brovo]A lot of evil characters are actually written poorly, often given no motivation for why they do the things that they do, or coming up with hair brained schemes that any fifth grader could defeat with a little bit of common sense. Most often evil is used as a shitscreen shield for doing random, depraved acts for no more reason than to be "edgy" or "cool". It's to the point that when people say they want to join any of my RP's with an "evil" character, I will probably shoot them down unless I know them well enough to trust them.Because, really, no, it's not cool to join a story for the sole purpose of wanting to murder your fellow players when that's not the purpose of the plot whatsoever.

This used to be one of my chief gripes. I once ran with this group where more than a few people would create, as I called them, "generic psychopaths". They generally just happened to be insane and capable of all kinds of cruelty, yet also balanced and logical enough to fight efficiently and make sound decisions in general. It was even worse when they made a small group of them that had no real reason to show loyalty to one another, but fought as a pack because, of course, they were all the writer's little pets >.> And naturally, they found any excuse they could to start a fight and get someone killed. No one ever seemed to get terribly fussed about it until they were explicitly targeted, though XD

It's been a really long time since I've actually encountered someone who's done this, however.
