not saying this should be implement just think its neat idea
say a certain % of the population was allowed to choose to be evil.
and once its full to become evil you must kill an evil(makeing that person become blue and you red)
think of being red like a buff that allows u to attack anyone. once you get killed by a someone without the buff(blue) u lose it and they gain it.
(also they could choose to not steal it)
this would make being red being the strongest and best fighters who were evil and the weak ones fighting reds to become evil. makeing it a previlage to be evil and killing blues instead of just a choice.
probly not the best thing for the game i just like the idea of fighting to be the strongest and evilest. and being red proves that your a force to be wrekkoned with. just an idea.
i dont think this idea would work with how the game is intended or setup but its interesting idea.
