Heheh, I like the idea of 'pupkillers' in roleplay. xD
I actually think pupkillers make roleplay a whole lot more fun, they make the whole plot much more exciting and dramatic. I always wanted to roleplay a pupkiller xD
Sure, it's kind of annoying when they godmod, powerplay, autohit and stuff, but that's just because they don't know how to roleplay fairly & properly. But hey, it's just roleplay fun, nothing to hold a grudge against in real life.
Relating pupkillers in real life, that is just creepy o_o . I mean, the whole idea is just wrong and cruel.
