my orientation is very close to zero because my hero is neutral!
and of course the closest to zero is the better for a neutral.

this means that the game's engine doesn't allow to maintain a team of neutrals?

I can't agree, if this is the choice, and I suggest to review the engine.
In fact a neutral balance between evil and good for a hero should be difficult to achieve (and of course very difficult for a team) and heroes with a neutral orientation should be awarded.
