So, what made you think people on this MUD are not nice? This cannot be seen well, as if you interact with evil characters or are one yourself, you are not going to find people being nice, as the characters you interact with are evil or you are one yourself and are treated accordingly. Would you be nice to a person whom you'd know to be a child molester or serial killer in real life? Your necro falls to that category. Thus, people are not nice to him.

Whether the players of the MUD are actually nice to you is seen from how you treat you after they PK you or vise versa or some other interactions, which evils are not so likely to get, as people don't often be nice when they play evils. So, I find your claim that people aren't nice in this MUD without base, as the OOC personalities are not supposed to come forth directly. You did probably read help permagroup, so the fact that the other char was played by your buddy isn't really a key factor here, IMHO.
