When I RPed a villain in TERA, most of her victims were NPCs; rather, they had to be: They were ether all corpses or soon to be. If I have my FFXIV character become more villainous, her targets will again be NPCs; can't play a serial killer if no one dies. In both cases, there were/will be times that my character would come into conflict with other people's characters, and I wouldn't expect anyone to willingly let me kill them. It's also why I really value OOC communication (and will never understand why people remove OOC communication channels from view when they're doing RP).
