One of my earliest cf memories is getting ganked by 3 evils and them leaving me my junk, telling me that the dark gods frown on weakness and that I needed to use my things to grow strong.

I quite often use that sort of argument to allow me to go easy on a newb I've just killed, because they are a newb. If you have a character whose role is to kill as many people as possible, that can best be achieved by multi-killing newbs, unless you choose to put a twist in your role that rules this out. Ultimately, role is flexible and down to you as the player to apply as you see fit. If you want to beat on newbs, don't blame it on your role; admit that you chose to have your role force you to beat on newbs.
