To be honest, as it is i don't think it's a very tough choice. The blue pill seems the much more attractive option.
Now... to make the choice a HARD one... Red Pill: You are evil to your core, but everypony adores you and you can't seem to do anything they'd find evil ( evil plans don't go according to plan because of this)
Blue Pill: You are a kind and benevolent ruler incapable of 'evil', but everypony hates you and you can't seem to do anything they find good. ( good deeds are met with cruel eyes and reactions)
You aren't given the option of not picking one. you have to choose, Red or Blue.
