exactly that's why you may know some already who knows how to rp and would like some evil people to insult their characters for some fun XD, however if a noob comes to you while buying or something and says "hi wit u how do i get a sword?" you will know at that second ok he is a noob but you have to respond to him... so /tell noob hello

what i am doing now is just IC so you shouldn't get offended OOCly to reply to me type "/tell evilguy <message here>"
noob tells you: wtf is IC
*explains.... an hour later*
noob tells you: sounds fun, try me (some understands it easier than others XD)
noob says: greetings sir, can you tell me where i could get a sword please?
evilguy says: why should i tell you bigheaded bootlicker?
noob says: because i need help in this world i don't know where to go or anything but it would be nice for me if i had a weapon to defend myself while tryign to explore on my own...
and so it goes on... and you should keep the ooc with him for a while to comment on his rp so he won't get offended oocly the first time he tried to rp. Something like you tell noob: nice phrase

.
Then you would most certainly get to talk about evil in the world a bit after in most occurances...
