I went through a phase something like this. I rolled up a human warrior chaotic evil and was something like 11 and 1 in pk's by rank 20. I hated the character and went back to goodies because if I am going to be in a fantasy I want to be the hero not the goat. Now, I get 5-20 solo kills per long lived character and am fine dying with grace. I am too old now to change and this is fine by me. I still get pissed when I get ganked or worse murdered by the self-reliant. But I get over it and play on. So, if you really want to be a murder pk'er it is not too difficult as long as you use cunning, corpse loot a hero or two and pick on the newbies. At hero you just need to hang out with the cool kids when they go looking for the phat loot for a couple of characters and learn the secret gear/places.
