Alot of what I see this is my opinion, and there are good arguements and opinions like gray ghosts, is this. I will be using his to counter, and some others are included. Yet overall this is what I see.
That because your not getting an immedaite satisfaction, or reward it's not a viable option. Yes we can add gray's points to counter. Yet again may imo simply want the rewards, and tadpole removed. Yes greed is supposedly evil. From this I gather that many are
A)looking for short term satisfaction, the quick and easy or
B) Remove my tadpole, give me riches, and treasure.
C) again easy path.
You don't want to aid the goblins because they attack you, your evil kill them, by doing so you prove to their boss your not to be trifled with, and will make a good underling (note your lvl 3 your not even near developed enough in your class to do mighty things) killing goblins no problem. Killing farmers, and unarmed people no problem, taking out certain druids again might be no problem. Yet in the long run your a fly that has it's uses. They know this even if you don't, yet you do have potential, and could eventually become a threat to their power. So you kill goblins (they breed like rabbits so always more) prove yourself to the Bosses, who are now willing to aid you if you aid them.
If the goblins simply let you waltz into their camp not knowing you, not knowing if your a threat, a potential and useful ally, then they would be stupid evil. If the Bosses simply helped you not knowing you, not knowing if your a spy for another enemy, or if you can be any use to them they'd be stupid evil. You as is argued by many, and a reason many are still following the good path are an unknown so aiding you for no reward is stupid evil. Why should they their not good they don't pass to coins to beggars, they may very well steal the beggars coin.
You say well I'm not getting a reward from it, and thats stupid evil. Whats the reward for them helping an unknown, nothing that they know of.
You argue - that evil is greedy self centered, and motivated by personal gain. True in large part I applaude you, but your failing to see that guess what, they evil people in the game are the exact same way.
So by your own logic, and arguements they would be stupid evil to do anything for you. Until you prove to them that your useful, and not just more trash they have goblins for that, and goblins breed far faster then the other races. Your not giving them a reward, unless you do something for them.
So you don't want to be stupid evil. I get that it's boring, and not very exciting. Why the hell should the enemies in the game be stupid evil??
Rant over. note this is a view from rp stand point, and not meant to inflame, debase anyone. Please feel free to prove me wrong, or agree up to you.
