Good and Evil aliens?

Hello I have been going through this in my head and was just wondering about your thoughts.

The two most known alien races are the Grey's and Reptiles/Reptilians, now is the general thought that the Grey's are trying to protect us from the marauding Reptiles, or is the other way round?

Good and Bad is a matter of perspective via viewpoint in association or conflict with a set of goals acchieved or in the process of trying to be acchieved.

Is the "human race" Good or bad?

Does an entire race have to be good or bad? Not from where I'm standing. What planet are you from?
